Catalog excerpts
Chlorination of potable water, wastewater effluent, and industrial cooling water is widely used throughout the world to control biological activity in the water. Disinfection of potable water with chlorine ensures that tap water is safe to drink after passing through the distribution system piping. Wastewater disinfection helps to ensure that receiving streams are safe for recreational use, and cooling water chlorination reduces biofouling that can degrade heat transfer efficiency. This wide use of chlorination for disinfection purposes results in the need for a reliable “residual chlorine” analyzer that can operate in a variety of applications.

Residual chlorine is found in many chemical forms in water systems. Residuals in clean water are often predominantly free chlorine while wastewater and cooling water can contain mixtures of free chlorine, combined chlorine, and organochlorine species. Measurement of residual chlorine in applications where only free chlorine (potable water) or only combined chlorine (chloraminated water) exist can often be monitored with direct sensor measurement. However, applications where a variety of chlorine forms can exist (wastewater effluent and some cooling water) require a more complicated...

FEATURES Gas Phase Sensing. Measurement is made without contact between sample and sensor, eliminating the potential for sensor fouling. Standard Method. Total Chlorine is measured using EPA recommended iodometric measurement after reaction of the sample with buffer and potassium iodide. Analog Output Options. Two isolated 4-20 mA outputs are standard. One output is programmable for PID function. Three Control Relays. Relays are programmable for setpoint, deadband, and time delay. Digital Communications. Communication options for Profibus-DP, Modbus-RTU, or Ethernet-IP. Clear Display....
