Chlorine residual analyzer AH-2003/10 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, 4.3" TOUCH SCREEN panel. This panel enables easy monitoring of measured residual and temperature, as well as upper and lower alarm point adjustment. All measured values are shown on integrated digital printer, and their record is made on the SD card in resolution requested by the user.

Operating principle
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 the front Touch screen panel, as well as on integrated digital printer. 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).
Temperature probe is embedded within the measuring cell, and measured temperature value can also be read on the display and integrated digital printer.

Chlorine residual analyzer AH-2003/10 has integrated digital printer which enables graphical display of measured values, a total of 4 values (in standard version – residual chlorine and temperature, and optionaly pH and Redox or other values, depending on user requirements). Graphical display of optional measurements (pH and redox) is not available if the option is not selected.
Each of the three measured values (residual, pH, Redox or other) is displayed on digital printer (with possible axis width from 3.5 minutes up to 14 hours) in function of temperature and with indication of alarm values.
All measured values are recorded on SD card with capacity up to 1GB.
The control interface is available in 6 languages: Serbian, English, German, Romanian, Slovenian, Hungarian (2 more languages are available on request)
