TDS Meter, Sonkir TDS01 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (White)

 Ean: 0767665663758   |    PartNumber: TDS   |   Asin: B07DN9WGPW

Backlight Warning Function
Refer to the international standard, TDS value of 40 is the critical point for the purity of water. The lower the TDS level, the purer the water.
If TDS value is above 40, normally it indicates the water is very likely unsuitable for drinking, and hence the backlight of the LCD will turn out to be red while the test result of TDS is above 40.
However, the water with TDS value below 40 does not necessarily mean it is drinkable since there are various factors (e.g. bacteria amount) would determine whether the water is safe or not.

Automatic Temperature Compensation (ATC) Function
Since TDS value would be affected by temperature, this meter is equipped with Automatic Temperature Compensation (ATC) function for the highest accuracy purpose.

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.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.

HealthSnap 3-in-1 Digital TDS | EC | Temp Meter, High Accuracy Water Hardness Test Pen 0-20,000 ppm - Rapid Testing of Drinking Water, Ground Well Water, Aquariums, Hydroponics, RO | DI Systems

 PartNumber: HSTECA01   |   Asin: B07GFPQY31

The HealthSnap 3-in-1 Extended Range TDS Meter was designed for instantaneous, reliable, and accurate testing for total dissolved solids (TDS), water hardness, electrical conductivity (EC), and temperature in a variety of water sources, including drinking water, ground water, well water, tap water, pool water, spas, hydroponics, aquariums, water filtration systems, and industrial water systems. Our ergonomically designed pen-style digital meter is carefully tested and calibrated and is ready for use right out of the box. A bright high-quality LCD display allows for easy visualization of the test result and a data HOLD button function allows you to freeze and save data measurements for easy reading and viewing of measurements post-testing. An auto-off function saves battery life by shutting down the meter after 5 minutes of inactivity. A premium titanium alloy electrode probe, proprietary Automatic Temperature Compensation (ATC) function, and state-of-the-art microprocessor technology allows for testing between 0-20,000 ppm TDS and 0-20,000 uS/cm EC, with HIGH accuracy at a variety of temperatures. Other competitor TDS meters only monitor 0-10,000 ppm and 0-10,000 uS/cm. To use, simply collect the water sample to be tested in a vial, cup, or container. Mix the sample, turn on the meter, remove the protective electrode cap, and dip the meter into the water sample up to the immersion line. Wait until the meter stabilizes and then collect the result. When done, wipe the electrode and replace the protective cap.

Features

  • 🚰 RAPID RESULTS: With a novel ergonomic pen-style design, our lightweight multipurpose meter allows for affordable and easy testing of all types of water sources including drinking water, ground water, tap water, well water, pool water, spas, hydroponics, aquariums, and industrial water systems. Easy interpretation - no assistance needed - no lab tests required.
  • 🚰 NEW EXTENDED RANGE MODEL: Our compact smartpen digital water meter allows for testing a large range of TDS and EC levels. Advanced technology, electronics and algorithms implemented in our meter allow for testing from 0-20,000 ppm TDS and 0-20,000 uS/cm EC. Other competitor TDS meters only monitor 0-10,000 ppm and 0-10,000 uS/cm.
  • 🚰 ACCURATE AND RELIABLE: Our TDS meter is equipped with a factory calibrated premium titanium alloy electrode probe. Together with our proprietary Automatic Temperature Compensation (ATC) function, and state-of-the-art microprocessor technology, our meter provides accurate TDS and EC readings at a variety of temperatures.
  • 🚰 EASILY KEEP TABS ON YOUR TDS LEVELS AND WATER QUALITY: Our portable meter will help you easily determine the total dissolved solids (TDS) and electrical conductivity (EC) of your water. Monitoring your TDS and EC water levels helps you keep tabs on your water hardness. This will help you determine the efficacy of your water purification, reverse osmosis, water softener and water conditioning systems.
  • 🚰 100% SATISFACTION GUARANTEED: We are here for you every step of the way. Please contact us for any questions you may have. If for any reason you're not satisfied with our product, simply return within 90 days for a full refund. No questions asked.
