Free Chlorine & Total Chlorine 

Do you require to measure Residual Chlorine, Chlorine Dioxide, Paracetic Acid, Hydrogen Peroxide or Ozone?

What is Free Chlorine?

Free Chlorine or Residual Chlorine: The amount of measurable chlorine remaining after treating water with chlorine i.e. amount of chlorine left in water after the chlorine demand has been satisfied.

What is Total Chlorine?

Total Chlorine is the total amount of chlorine found in water ie: the sum of Free Chlorine or Residual Chlorine and The Combined Chlorine.

Our new DOSAcontrol multi function controller will give you the results you require at a very competitive cost! The ME5090 can be configured through easy to use software within the controller as:

  • pH
  • Redox
  • Chlorine
  • Chlorine Dioxide 
  • Paracetic Acid
  • Hydrogen Peroxide
  • Ozone  
  • Temperature

Replacement Sensors and Ancillaries:

Do you require to monitor your level of water disinfection? Following an extensive research program, We are pleased to announce a new range of robust, industrial disinfection probes for measuring Chlorine, Chlorine Dioxide, Hydrogen Peroxide, Ozone and Peracetic Acid Probe designed for the analysis of potable water, swimming pools and water for industrial use, the following probes are now available:

Residual Chlorine Monitor

It is important for us to ensure that the water we use is free of impurities. A residual chlorine monitor is one of the most useful devices to ensure the chlorine levels in water are not hazardous. A residual chlorine monitor also helps to monitor and control chlorination systems.

Total Chlorine Analyzer

A total chlorine analyzer is one of the most important devices used to measure the level of chlorine contained in water. This device is used in many water treatment industries to purify water that is essential for different uses. A total chlorine analyzer can ensure that water is completely safe for all uses.

Chlorine Analyser

Whether it is for sewage purification, fish farming or your swimming pool, a total chlorine analyzer is an important device to have to ensure that the water you are using is treated efficiently. A total chlorine analyzer can produce accurate data regarding chlorine levels in the water so that it can be effectively sanitised if required.

Chlorine Dioxide Measurement

Everyone knows that chlorine dioxide is not good for human health. For this reason it is important that we ensure the water we are using is treated of high levels of chlorine dioxide. It is here that a chlorine dioxide measurement device can be very handy. Chlorine dioxide measurement is used mainly to disinfect drinking water.

Water Analysis

Analysing the water we are using on a daily basis is necessary to keep us away from health disorders and sicknesses. At Russell Mainstream Supply we offer a number if water analysis devices that can help test and treat various water impurities. Our water analysis instruments are ideal for using in laboratories as well as field activities.

Hydrogen Peroxide Detection

As the world is aware of the harmful effects of hydrogen peroxide. Hydrogen peroxide detection in water is vital to keep illnesses at bay. Here at Russell Mainstream supply we ensure that our hydrogen peroxide detection devices can help you in your water treatment efforts.
