This is a Chemtrol Bromine PPM Sensor, no wire, with 0-010 ppm readings. To calibrate the Bromine PPM sensor use a Bromine test kit. The new Chemtrol PPM solid state sensors feature superior precision and control of chlorine levels, with industry leading reliability and low maintenance requirements. These probes are so precise and reliable that they are covered by a 2-year warranty.
The PPM sensors can be used alone or in combination with an ORP sensor to give the operator complete control of water quality. For better water management results, it is recommended that you use ORP control of chlorine oxidizing activity and PPM monitoring of total chlorine. Alternatively, PPM control can be used for control of the sanitizer and ORP control for a non-chlorine oxidizer.
The sensors are designed to be installed in a specially created flow cell for controlled flow of water. The recommended flow rate is about 15 gallons per hour. They are shipped in a molded foam package containing: One chlorine sensor, one compression fitting with o-ring and compression disk, one electrolyte cap with membranes, one electrolyte bottle and screw on filling tip, and one screw driver (not needed if pre-wired). Be careful not to touch the membrane or the electrodes. Before installing sensor cap, fill with the electrolyte solution. The solution is emptied during storage.
