CHEMTROL FREE-CHLORINE SENSORS

PARTS

Chemtrol™ PPM Sensors Introducing new PPM sensors for direct

• Free chlorine measurement including: free chlorine (HOCl and OCL-) and combined isocyanurates if present, corresponding to the DPD1 test. • pH Range of 5.5 to 9.5 • Temperature range of 5 to 50 C (40 to 120 F) • Cyanuric acid compatible, • Pressure range up to 3 bars (45 psi) • PVC body with 1" MPT fitting • Replaceable membrane and electrolyte

measurement of FREE CHLORINE in water in parts per million (ppm) or milligrams per liter (mg/l). Unlike other chlorine sensors on the market, these sensors are very precise and so reliable that

they are covered by a 2-year warranty. They are easy to install and practically

maintenance free. For best water management, it is recommended to use ORP control of chlorine oxidizing activity and PPM monitoring of free chlorine. Alternatively, PPM control can be used for control of the sanitizer and ORP control for a non-chlorine oxidizer. PPM, ORP and pH

For best results in water management, it is recommended to use both ORP control of free chlorine and PPM monitoring of total and combined chlorine. Alternatively, PPM control can be used for control of the sanitizer and ORP control for an oxidizing agent, such as ozone. The chlorine sensor is now available with the CHEMTROL(R) 255T Digital Controller for PPM and pH.
