Chlorine residual analyzer AH-2003 has been tested and proven as a reliable device for continuous and accurate measurement of the residual. The device works on the amperometric principle and it is designed to continuously measure free chlorine in the water, swimming pools or in various process applications. The measuring cell is equipped with built-in continuous electrode hydraulic cleaning system with rotating balls, which eliminates signal interference and need for frequent analyzer recalibration. Integrated two-point alarm (high and low residual) is standard. Sample is brought through the control valve which eliminates the need for special sampling pumps. Gold and copper electrodes of large areas are used to obtain maximum signal strength. The device is made of anti-corrosive materials. Each unit is pre-assembled, requiring only the connection of sampling lines.
Components and controls are available on the front panel enabling easy monitoring of the measured residual, sample flow rate, electrode cleaning system and adjustment of upper and lower alarm points.

Water sample, with unknown chlorine content, is brought into the measuring cell. Using the amperometric method, the measuring cell generates an electrical signal proportional to the chlorine content. This signal is converted by the transmitter into a current signal 4-20 mA. Measured value is displayed on integrated digital display on the front panel, as well as on optional remote pointers, printers etc. Residual chlorine concentration can be regulated in the preset limits (built-in relay contacts are turned on at particular, preset minimum and maximum chlorine level).
