Chlorine gas detector is designed to detect the chlorine presence and to continuously measure chlorine concentration within the zone under supervision (for example, room with chlorine dosing equipment or storage room for full / empty chlorine cylinders). It is capable to detect very low chlorine concentrations, below 0.5 ppm. This device allows the user to set up two completely independent alarm levels, at which will be activated two independent relay contacts, that can turn on external sound / light alarm devices, fans or special devices for the automatic neutralization of chlorine present in the air. Measured concentration is shown on the detectors display in the range of 0 – 10 ppm.
The device consists of two parts: measuring sensor – chlorine detector probe HS-25-09 and electronic microprocessor receiver – chlorine detector DH-2003.
Characteristics:
- Measuring range: 0-10 ppm
- Measurement resolution: 0.01ppm
- Chlorine detector probe with transmitter
- Response time: 50sec
- Digital LED display
- Independent adjustment of two limits
- Light indication alarm
- Indication of probe failure
- Continuous measurement of chlorine in the air
- High reliability
