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.
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.

Sanitary Conductivity Sensors
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 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.
