The Hypochlorite Sensor is used with the Chemtrac HydroACT analyzers for the measurement of chlorine in industrial bleach (sodium hypochlorite). This optical sensor, with a range of 0-16%, is specifically designed to withstand the harsh chemical environment associated with industrial bleach. The sensor is insensitive to changing pH, uses no reagents, is extremely stable, and has low maintenance
costs. A built-in temperature sensor allows for automatic temperature compensation.

Overview
PRINCIPLE OF OPERATION
The optical sensor shines light of a specific wavelength (near UV) through the sample, and the amount of light that is absorbed is proportional to the concentration of chlorine in the sample. The sensor has a reference light source and detector for stability, and an built-in temperature sensor for integrated temperature compensation.
The bleach keeps the sensor clean, and bubbles are encouraged to flow through the sensor, and will not settle on the optical surfaces since the flow orientation through the T-fitting is vertical.
Calibration is done with comparison to titration kits, and is generally performed on a 3 or 6-month schedule. Calibration input is via a simple wizard on the controller display.
ANALYZER INTEGRATION
The Hypochlorite Sensor integrates with the HydroACT Series of analyzers using Modbus, which gives full communication with the sensor. Please see the reverse side of this product sheet for details pertaining to I/O, communications, control, and remote access capabilities of the different analyzers offered.
