Addressable gas detectors GS-300.N are intended for detection and measurement of refrigerant gases.
Different principles of detection with semiconductor or electrochemical sensor elements are used.
Reliable operation of the sensor is guaranteed by the self diagnostic function.
The condition of the sensor element is constantli monitored and alert is activated in case of fault.
Sensor calibration is done remotely with magnetic key without opening the enclosure that facilitates periodic test and callibration.
Gas detectors GS-300.N are in IP65 rated plastic housing.
| Application | |||
| Addressable gas detectors GS-300.N are designed to monitor the concentration of freons and ammonia. | |||
| Along with addressable gas controllers GA-ADR.E1 they can be integrated into the overall building automation system. | |||
| Detected gases | Formula | Measuring range | Order code |
| Ammonia | NH3 | 0-100 ppm | GS-300.N |
| R-134a | C2H2F4 | 0-2000 ppm | GS-300.N |
| R-404a | multicomponent | 0-2000 ppm | GS-300.N |
| R-407c | multicomponent | 0-2000 ppm | GS-300.N |
| R-410a | multicomponent | 0-2000 ppm | GS-300.N |
| R-290 | 0-2000 ppm | GS-300.N | |
| Sensors for gases, which not exist in the table are made with preliminary order. | |||
