Chlorine sensors: Our chlorine sensors measure a wide range of concentrations of chemicals in water, and indirectly help prevent the growth of microorganisms. This is done without the use of reagents. These amperometric chlorine sensors can be used with all of our controllers for chlorine residual measurements in accordance with EPA Method 334.0.

Chlorine dioxide sensors: These are specialised sensors used to measure the concentrations of chlorine dioxide in water.

Stabilised bromine sensors: The sensors continuously and directly measure the chemical concentration, without the use of reagents. These sensors can work effectively even where ORP sensors and other amperometric sensors cannot reliably and repeatedly measure bromine that is stabilised with sulfamate. These are amperometric 3-electrode sensors and are widely used for cooling tower applications. They can withstand temperatures up to 45 °C (113 °F) and pressure up to 90 psi.

Total Chlorine: Our total chlorine sensors use microporous, hydrophilic membranes that allow measurement of all chlorine molecules, free or combined.
Peracetic Acid: The peracetic acid sensors are frequently used in food processing applications and can measure up 20,000 mg/l in water with a pH below 6.

Non-membrane sensors are used for the disinfection of hot potable water systems as currently required by the new ASHRAE standards of up to 70 °C (158 °F) in hospitals, schools, universities. The sensors support high pressure sample loops where the water cannot be discharged to open atmosphere (up to 8 bar (117 psi)) such as hot tubs and cooling towers.

• Free Chlorine and ClO2 sensors
• Designed for higher pressure and temperature, clean water applications
• Amperometric 3-electrode sensors
• The measuring and counter electrodes are in direct contact with the sample
• The reference electrode is isolated from the water by an electrolyte-filled housing
