Water-Resistant Dissolved Oxygen Meters

Check the oxygen levels of water and other clean liquids in harsh field conditions. This meter has a housing that meets IP57 for good resistance to dust and protection from temporary submersion. It has automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use distilled water and the calibration button to maintain accuracy.

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.

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

For Testing Conductivity, Salinity, Temperature, and Total Dissolved Solids (TDS)

Image of Product. Front orientation. Chemistry Meters. Remote-Reading Multifunction Chemistry Meters , For Testing Total Dissolved Solids (TDS).

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.

Remote-Reading pH Meters with PC Output

Transmit pH readings to a PC for analysis. These meters have a sensor on a 6-ft. cable for taking remote readings of water and other clean liquids. They have automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate readings in fluctuating temperatures. Use the included calibration solution and calibration button to maintain accuracy.
