Plastic pH Test Strips, Universal Application (pH 0-14), 100 strips

 Ean: 0013189988144   |    PartNumber: LRS-4801   |   Asin: B00X9D4JS4

This product contains one case of 100 plastic pH test strips. Each pH strip has four pieces of pH paper that will change color after being submerged in a solution. Each piece of pH paper has its own pH range and will change color accordingly. After submersion, the strips can then be compared against the color chart on the case to determine the pH. This method allows for fast and accurate pH readings. To further the reliability of our products we randomly test each shipment we receive across multiple pHs to ensure product quality and reliability.

Instructions:
1. Take one strip from the case and dip it into the solution you would like to measure. The colors of your strip will change instantly. Please note that not all two/four pieces of pH paper on your strip will change color - each piece has its own pH range and will change color accordingly. If testing saliva, do not put the strip into your mouth!
2. Quickly match these colors against the color chart on the front and back of your case to obtain the pH. Do not wait or let the strip dry!
3. The number above the matching colors on the chart is your pH. Any solutions with a pH beyond the pH range of your product will render inaccurate results.

Store in a cool, dry place away from sunlight.

100 Bartovation Chlorine Test Paper Strips For Testing Sanitizer Strength, 10-200 ppm

 Ean: 0643845994754   |    PartNumber: bart-cl   |   Asin: B01ETS3TYW

Chlorine Test Paper This Chlorine Test Paper provides a simple, reliable, and economical means to measure the concentration of free available chlorine in sanitizing solutions.The Chlorine Test Paper measures total available chlorine from 0-200ppm, and give results in just seconds. Total available chlorine is the sum of free available chlorine and the combined available chlorine. Our chlorine test paper is most often used to test the strength of solutions used to sanitize surfaces, for example, in the restaurant industry. In these types of applications, bleach is usually used to generate the available chlorine. When using bleach as a cleaner, it must be diluted before use, and it will work best in the pH range of 5-7. Instructions: 1. Use dry fingers to remove a chlorine test paper strip from the vial. 2. Dip the test strip into the solution to be tested, and do not agitate. 3. Remove and compare to the color chart immediately. NOTE: The strip will darken over time, so it is best to compare to the color chart as directed. In addition, if two strips are stuck together, the color will be darker. Lastly, if you lay the strip against the vial when comparing to the color chart, it will also darken the color. The color chart was created by holding a strip in the air next to the vial. IMPORTANT NOTE: this strip was designed specifically for restaurants to test chlorine sanitizers in three part sinks. It will work for testing anything in the range of 10-200 PPM. IT WILL NOT work for testing tap water, pool water, undiluted bleach, or anything that uses Quaternary Ammonia as the active ingredient. If you have questions about your application, please message us and one of our experts will be happy to help!

Litmus pH Test Strips | (pH 1-14), Universal Indicator, 2 Packs of 100 Strips. Test and Track Your Water, Diet, Saliva, Pool, Aquarium, Urine, Soil, and Kombucha Brewing.

Model: STR-01828   |    Mpn: STR-01828   |    Ean: 0011922964783   |    PartNumber: STR-01828   |   Asin: B0746HL482

Professor H says that there is a strong correlation between the pH of the body's internal environment and that pH paper can help you maintain a good healthy body by testing many usual everyday substances, including soap, lemon juice, milk, liquid detergent, moisturized soil, saliva, urine, sweat, etc.

PH papers are paper infused, or saturated, with pH indicators or more frequently, a mixture of indicators. They are used to test for alkaline or acidity of a solution or substance such as soil. pH papers are usually sold as strips. These strips of paper (or sometimes fabric) change color when they come in contact with the material or solution being tested. To use it, you immerse it in the material or solution, wait for the number of seconds listed on the instructions, remove the paper and compare the color change to a scale. The scale will tell you if the substance is acidic or alkaline, and to what degree. The indicators infused into the paper are predominantly weak acids. These acids react by changing color when they encounter substances with a certain pH value. For example, litmus, which is a natural indicator, turns red when it contacts something acidic and blue with alkaline materials. Often, indicators are mixed to create something called a universal indicator, which can change to several different colors to indicate a wide range of acidity; usually from pH2-10. Most pH paper strips are impregnated with universal indicators.

Instructions:
1.Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.
2.Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait
3.The number next to the color on the chart is your pH. The pH scale ranges from 1 (acidic) to 14 (base).

Please note that solutions with a pH of 5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.

Features

  • 200 Strips Total: Sold as Two Packs of 100 pH Strips. Great for testing items around your house, work, classroom, and your diet.
  • PH 1-14 color chart in each pack. Easy to use and the results come in just a few seconds. Each pack comes with simple instructions on the back.
  • Professor H says, If your pH is too acidic it can cause: Energy drain, Headaches, Indigestion, Bone Degeneration, Muscle Loss, and Insulin Sensitivity that results in Weight Gain and increased risk for Diabetes. If your pH is too alkaline it can cause: Nerve and Joint Pain, Arthritis, Insomnia, and Body Stiffness.
  • The pH value of a neutral solution is 7.0 at 25 C (standard laboratory conditions). Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic (alkaline). Test your solutions today!

pH Test Strips for Kombucha Brewing 0-6 (0.5 Intervals) 100pc Kit

 PartNumber: KC1001   |   Asin: B07DTH14XZ



It's important to test the pH of your kombucha both at the start and end of the 1st ferment

Testing before
For a safe brew that free from harmful microbes, ensure that the starting pH of your kombucha first fermentation is 4.5 or below
Note: If you need to lower the pH, mix in small amounts of plain white vinegar. Retest until you reach a pH of 4.5 or below

Testing After
The target pH for kombucha that's ready to drink or bottle is 2.5-3.5


Kombucha Chemistry strips are ready to use straight out of the box

No fiddly scraps of test paper to cut to length or tear-off
No finger or bench staining to worry about
Just test your booch and drop the used strip in the trash


Each strip measures

- 3.13" total pH strip length
- 2.63" white cardboard
- 0.5" test area


1-year's supply

If you brew once a week and test before and after your 1st ferment. This pH testing kit will last you a whole year (allowing for a 2 week brewing holiday)


Includes an easy reference color chart for 0-6 (0.5 intervals) and pH matches

0.0
0.5
1.0
1.5
2.0
2.5
3.0
3.5
4.0
4.5
5.0
5.5
6.0



*NOTE

Test strips with 1.0 intervals (i.e. 1,2.3..) are not precise enough to safely test kombucha. This is because of the importance of your brew's first ferment starting pH at or below 4.5 and 3.5 on finishing, 1.0 increment strips will not provide this accuracy.
Always use test strips with 0.5 intervals to safely test your home brewed kombucha

Features

  • Designed for kombucha: Pre and post 1F pH testing
  • Accuracy: kombucha pH testing at 0.5 interval markers
  • Thick individually cut strips: No cutting or tearing needed
  • Quick: Check the safety of your brew in 5 seconds

Watersafe WS425W Well Water Test Kit

Model: WS 425W   |    Mpn: WS-425W   |    Ean: 0163121151287   |    PartNumber: WS-425W   |   Asin: B00028PDO8

Watersafe Well Water Test Kit 1 KitProduct Description Kit Contains (1) Bacteria Test Vial (1) Lead / Pesticide Test Strip (1) Nitrate / Nitrite Test Strip (1) pH / Hardness / Chlorine Test Strip (1) Copper Test Strip (1) Iron Test Strip

WHY WATER TESTING ? Water is by far the most ingested substance on the planet. Even with modern water-treatment facilities, water can be a significant source of dangerous contaminants, spreading acute and chronic diseases. Continual exposure to certain man-made chemicals can be highly insidious, causing damage over months or years with often serious and sometimes deadly effects. Chlorine, used for disinfection in many commercial and residential facilities, can react with organic matter to form cancer-causing trihalomethanes. Even naturally occurring contaminants can show up in drinking water with deadly consequences. According the Center for Disease Control and Prevention, E. coli bacteria is responsible for an estimated 73,000 cases of infection and 61 deaths per year in the United States. Lead is toxic when ingested and causes a wide variety of systemic and developmental problems in adults and children yet this metal can leach from old pipes and fixtures, making its way into drinking water. Many homes and offices built before 1988 may have lead-containing pipes and fixtures still in use. In the US, about 1,000,000 children under the age of six have an amount of lead in their blood that exceeds the level of concern. Pesticides have been discovered in every large watershed in the US. The dangerous synthetic chemicals used in pesticides have also been detected in an alarmingly high percentage of groundwater wells in the US.

Test for copper, iron, and lead Detect dangerous levels of Nitrates/Nitrites Test for potentially harmful bacteria Reveal the presence of toxins from pesticides or fertilizers Learn your water's pH balance Determine your water's "hardness" Identify

Features

  • Fast, accurate, easy to use; compare results with EPA recommendations
