Test temperature, chemical concentration, contamination, and salt levels in liquid from up to 6 ft. away, then send the results to your computer for analysis. These meters include a USB cable that transfers up to 1,000 readings. Often used to test water quality, they work on both clean and dirty liquids—from tap water to wastewater. Conductivity tests measure the concentration of salts, nutrients, chemicals, and other substances. Total dissolved solids (TDS) tests report contaminant levels. Salinity tests determine the salt levels in liquid. The sensor is made of stainless steel, so it’s durable and resists breaking. IP67 rated, these meters are dust tight and withstand temporary submersion.

To prevent inaccurate results from changing temperatures, these meters automatically standardize temperature readings at 77° F. Temperature readings appear on screen with other measurements, so you won’t have to scroll through multiple screens. A data hold function freezes the current reading on the display.

To maintain accuracy of the meters, they come with calibration solutions and have a calibration button.

These meters cannot be sold to Canada due to import regulations.

Check the pH and conductivity of water and other clean liquids with one bench-top device. This meter has automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a Calibration Solution (not included) and the calibration knob to maintain accuracy.

Import regulations restrict sales to the listed areas.

Take multiple water-chemistry and temperature measurements in hard-to-reach places from up to 3 feet away. Often used in tap water and wastewater, these meters work in both clean and dirty liquids. Automatic temperature compensation standardizes readings to 77° F to prevent inaccurate results in changing temperatures. The data hold function freezes the current reading on the display. For easy viewing, temperature and chemistry measurements appear on the same screen. These meters are IP57 rated, so they resist dust and withstand temporary submersion. They cannot be sold to Canada due to import regulations.

To maintain their accuracy, all have a calibration button and some also come with calibration solutions.

Conductivity, salinity, temperature, and total dissolved solids (TDS) meters take four measurements at once. Conductivity measures the concentration of salts, nutrients, chemicals, and other substances. Salinity measures the amount of dissolved salts. TDS determines the contaminant levels. The stainless steel sensor is durable and resists breaking.

Don’t worry about dropping this meter in your tank when checking electrical conductivity—it floats and has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion. For use with water, hydroponic solutions, and other clean liquids, this meter measures a liquid's conductivity to indicate the concentration of salts, nutrients, chemicals, and other substances. It displays temperature in addition to conductivity. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a Calibration Solution (not included) and the calibration button to maintain accuracy.

Import regulations restrict sales to the listed areas.

Turn pumps, mixers, valves, and other equipment on or off based on the conductivity of a solution. These controllers compare input from a sensor (sold separately) to a programmed actuation point and turn equipment on or off when the reading reaches the actuation point. They have two control relays. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures.

Test for contaminants before installing water-treatment equipment such as boilers and filters. You can also check your pipes and equipment for improper chemical levels that can cause corrosion and scale buildup, shortening their life.

367-test kits include tests for six common water-quality parameters in boiler systems and cooling towers.

340-test kits include tests for monitoring municipal water, which is often treated with chlorine.

290-test kits include tests that help you monitor well water, which often contains sulfur compounds.

All the chemicals and labware you need for on-site sampling and water-quality testing.

Digital kits offer simpler and more accurate testing than analog kits. While analog kits require you to visually match color against a chart, these kits electronically measure color for you, even in dim lighting. The digital screen shows you a precise measurement.
