Non-Membrane Disinfection Sensor

Disinfection sensors are used to detect the level of oxidisers in water treatment processes

Types of disinfection sensors and what they measure:

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

Key benefits:

  • Fraction of the price of previous matched design
  • Drop in replacement to older units
  • Accepts both U.S. & metric tubing
  • Designed, developed & made in the USA
  • Works with Non-Membrane Disinfection Sensors

Key Features of Non-Membrane Sensors:

Here are some benefits of using non-membrane sensors, especially for chlorine applications and high pressure sample loops where the water cannot be discharged to open atmosphere:
  • These sensors are extremely efficient when measuring free chlorine and ClO2 levels in drinking water.
  • Non-membrane amperometric chlorine sensors can be used for chlorine residual measurements in accordance with EPA Method 334.0.
  • An electrical signal which is proportional to the concentration of the disinfectant is generated at the measuring electrode. The measuring signal is temperature compensated.
  • Amperometric sensors perform best in drinking water or any clean water application with near neutral pH, and are typically used in higher pressure and/or temperature installations.
  • These are amperometric 3-electrode sensors, wherein the measuring and counter electrodes are in direct contact with the sample.
  • These sensors can withstand pressure up to to 8 bar (117 psi).
  • The reference electrode is isolated from the water by an electrolyte-filled housing.

Typical applications:

If you need to measure the chemical levels in your process or even drinking water, these disinfection sensors are extremely useful. They're an integral part of our water treatment controllers.

We can provide various types of disinfection sensors that can be integrated to water treatment controllers as part of an effective water treatment process. These can be customised to suit specific client requirements.
Here are some application areas of our disinfection sensors, depending on their type:
  • Drinking water
  • Food processing
  • Reuse and process water
  • Swimming pools
  • Cooling towers
  • Bottle washing
