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.

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.

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.

Oxidation reduction potential (ORP), pH, and temperature meters take three measurements. ORP measures the amount of dissolved oxygen in liquids. It determines how efficiently a liquid breaks down contaminants.

The remote sensor with a cable lets you take pH readings in hard-to-reach areas. Made of durable nonglass, it resists breaking. These meters are for use with dirty liquids, so they stand up to petrochemical, environmental, and agricultural testing. The water-resistant housing meets IP65 for protection from dust and low-pressure washdowns. Use the included calibration solution and calibration button to maintain accuracy.

These meters cannot be sold to the areas listed due to energy or import regulations.

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.

Check pH in harsh field conditions. These floating meters that have a housing that meets IP67 for complete resistance to dust and protection from temporary submersion. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a calibration solution and the calibration button to maintain accuracy. They do not include Calibration Solution. Meters cannot be sold to Canada due to import regulations.

Meter for clean liquids is commonly used in pools and hydroponic solutions.

Meter for dirty liquids stands up to wastewater, plating bath solutions, and other harsh liquids.

Since this oxidation reduction potential (ORP) meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion, it’s often used to determine a solution’s ability to break down contaminants in harsh field conditions. For use with dirty liquids containing heavy metals, sulfides, and harsh chemicals, this meter is often used for wastewater treatment. 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. Meters cannot be sold to Canada due to import regulations.

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.

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.

Since these meters float and have a housing that meets IP67, they won’t be damaged by temporary submersion and have complete resistance to dust. They detect total dissolved solids (TDS) in water, hydroponic solutions, and other clean liquids to determine contaminant levels. 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.

Often used to save rinse water in beverage and pharmaceutical lines, these sensors test the amount of chemicals, cleaners, and other substances in liquids by measuring how well the liquid conducts electricity. They’re 3-A and European Hygienic Engineering and Design Group (EHEDG) certified, thanks to their design that’s easy to keep clean. Highly polished, they limit where bacteria could grow. They also withstand washdowns with hot water, chemicals, and cleaners common to sanitary lines because of their PEEK probe, stainless steel body, and IP ratings. Their IP ratings also mean they’re dust tight and won’t fail if briefly under water. All are FDA compliant to safely touch food.

These sensors work with IO Link, Hart, and 4-20 mA analog output to connect to remote displays and programmable logic controllers (PLCs), making them good for hard-to-reach areas and frequent application changes. This also means they’ll set off alarms and trigger cycles to start and stop in automated systems. With the touchscreen, program each color of the display to alert you to errors, completed cycles, and other events. Both the head and the display rotate to view readings from the best angle.

Highly accurate, these sensors test almost any liquid. They also measure temperature—no need for a separate sensor. To compare readings as temperature changes, they automatically standardize readings at 77° F. All meet European safety standards, since they’re CE marked.

Use quick-clamp adapters to connect these sensors to quick-clamp sanitary tube fittings.
