Clean and
Dirty Liquids
Test different water-chemistry measurements in dirty, wet conditions. Often used in pools and spas, all of these meters are for use with clean liquids. 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.
IP57 meters are protected from dust and temporary submersion in liquids.
IP65 meters are protected from dust and low-pressure jets of liquids.
Conductivity, salinity, and total dissolved solids (TDS) meters come with one sensor that takes all three chemistry measurements.
Conductivity and total dissolved solids (TDS) meters come with one sensor that takes both chemistry measurements. You can also use them in aquaculture solutions, wastewater, and other dirty liquids.

Remote-Reading Multifunction Chemistry Meters
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.

Remote-Reading Multifunction Chemistry Meters with PC Output
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.

Bench-Top TDS Meters
Commonly used to test environmental samples, boiler condensate, wastewater, and other dirty liquids for contaminants, this bench-top meter determines the total dissolved solids (TDS) in a solution. It 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.
