Apera Instruments PC60 Premium 5-in-1 Waterproof pH/EC (Conductivity) /TDS (ppm) /Salinity (PPT) /Temp. Multi-Parameter Pocket Tester Kit, Replaceable Probe

Model: AI316   |    Mpn: AI316   |    Ean: 0858718006094   |    PartNumber: AI316   |   Asin: B01ENFOIKA

The Apera Instruments PC60 Multi-parameter Tester simply tests pH, EC (conductivity), TDS (ppm), salinity (ppt) &temperature in a highly quick & professional manner for all kinds of general water solutions such as hydroponics, horticulture, aquaculture, pools& spas, drinking water, water treatment, cooling towers, environmental monitoring, education, etc. The multi-parameter probe is replaceable and easy to install. 1 to 3 points of Auto Calibration and 0 to 50 C Auto Temperature Compensation (ATC), 0. 01 pH, 1% F. S, 0. 5 C accuracy with -2. 00 to 16. 00 pH & 0 to 20. 00 mS/cm measuring range, auto recognition and reminders of stable values improves consistency, saving you the trouble of guessing when to manually hold measurement (auto. hold function available). Easy menu setting, customizing your tester s functions according to your needs. Smart self-diagnosis, warning of out-of-range measurement and incorrect calibrations. IP67 waterproof and dustproof, floating on water so you don t have to worry if it falls into water by accident. Up to 1000 hours' continuous operation (without backlit) powered by AAA batteries (with low power warning and auto power off in 8 min if no operation)es with a complete kit of premixed calibration solutions (4. 00 and 7. 00), soaking solutions (3M KCL), calibration bottles, AAA batteries, and a lanyard all in a portable carrying case. The meter is CE certified and comes with a 2-YEAR (6 months for the probe). NOTES: The instrument will NOT perform well for distilled or deionized water's pH measurement ( works well for conductivity). This is because distilled and deionized water do not have enough ions present for the electrode to function properly in pH measurement. To measure distilled or deionized water s pH, users need to use a specialized pH meter such as Apera SX811-PW. Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for rinsing the probe.

Features

Hanna Instruments HI98128 pHep 5pH/Temperature Tester, 6-25/64" Length x 1-19/32" Width x 1" Height

Model: HI 98128   |    Mpn: HI98128   |    Ean: 0793573622440   |    PartNumber: HI98128   |   Asin: B0085WV6GM

The Hanna Instruments HI 98128 is a compact pH tester used in laboratory and industrial applications, and has Automatic Temperature Compensation (ATC), automatic calibration, a dual-line LCD screen, a replaceable electrode cartridge, and a housing that floats. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications.

The dual-line LCD screen simultaneously shows the current measurement and the current temperature, and a hold function freezes readings for recording. The meter has automatic calibration at one or two points with two sets of standard buffers (pH 4.01/7.01/10.01 or pH 4.01/6.86/9.18). The meter has a water-resistant housing, a tactile grip casing, and floats. A battery error prevention system alerts when battery power is low and displays battery percentage on startup. Four 1.5V AA batteries provide approximately 300 hours of continuous use. The meter switches off after eight minutes of inactivity to save battery life. The meter also comes with a HI 73127 pH electrode, an electrode removal tool, and instructions.

Specifications pH range -2.00 to 16.00 Temperature range -5.0 to 60.0 degrees C (23.0 to 140.0 degrees F) pH resolution .01 Temperature resolution 0.1 degrees C (0.1 degrees F) pH accuracy + or - .05 Temperature accuracy + or .5 degrees C (1 degree F) Operating temperature -5 to 50 degrees C (23 to 122 degrees F) Operating relative humidity 100 percent Dimensions 163 x 40 x 26mm/6.4 x 1.6 x 1.0 inches (H x W x D) Meter weight 100g/3.5oz. H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.

What is DTS and why should you care about it?
TDS means Total Dissolved Solids, expressed in units of mg/L or parts per million (PPM), which is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular suspended form. The lower the TDS level in the water, the more efficiently your body cells can use the water. With this you can have a clear mind of water status and take measures to guarantee water safety for your family. TDS meter is a also great tool to test how your RO water purifier is working.

*Measuring Range:
TDS: 0 - 9999 ppm (PPM)
Conductivity: 0 - 9999 s/cm
Temperature: 0-99 C (32.0 - 212.0 F)
*Accuracy: 2% F.S
Size: 6.37 x 1.14 x 0.59 inches
Weight: 2.33oz

Features:
* Automatic Temperature Compensation (ATC)
* Backlit LCD:
If TDS 40, the backlit color is green,
If TDS>40, the backlit color is red.
* Auto-Lock Function: The reading will be stabilized in seconds, and locked automatically for easy reading and recording.
* Hold Function: The reading can be locked manually by pressing "HOLD".
* Factory Calibrated: ready to use right out of the box.
* Auto-Off in 2 Minutes to save battery power.

TDS Meter ATC Water PPM Value Conductivity Temperature 3in1 Large Screen Backlight 0-9990PPM Accuracy 1% Drinking Water Aquarium Swimming Pool Hydroponics Brewing (Yellow)

 Ean: 0735314074453   |    PartNumber: K20   |   Asin: B07RYRL45V

Ppm is the unit of hardness of water. Hardness refers to the concentration of calcium and magnesium ions in water. 1 ppm represents the content of calcium carbonate in water of 1 mg/L. When the concentration of Ca and Mg in water is lower than 80 ppm, it belongs to soft water. The higher the PPM value, the higher the hardness of water, the longer the drinking water will be, which will lead to calcium precipitation in the body and cause stones and other symptoms TDS meter is suitable for all water purification applications, drinking water, water filtration and purification, hydroponics (testing nutrients), colloidal silver, aquarium, swimming pool and spa, etc. (TDS meter can only detect soluble solids in water, but can not detect water pollution) Tip: TDS meter has been strictly calibrated and can be used directly to avoid operating errors in the complicated calibration process

Features

  • Various functions: TDS meter integrates various functions, testing water hardness (PPM), conductivity (US/CM) Fahrenheit Celsius . All four sets of functions are focused on this TDS meter to meet your various needs
  • Automatic temperature compensation function: TDS meter built-in ATC automatic temperature compensation function, so that you do not have to worry about testing the temperature of the liquid, to ensure that at all temperatures, the data is always accurate
  • Special Titanium Alloy Probe: Special Titanium Alloy Probe can detect data more quickly and accurately
  • Large LCD screen: In order to make the old people with poor eyesight, or you work in the dark environment, can also clearly see the detected data, TDS meter installed large LCD screen, the screen is clear
  • Intelligent lock reading: Just turn on the TDS meter and put the front end into the test liquid, you can quickly get the data you want, and the TDS meter can automatically lock the detected data for you to watch at any time
