External hydrogen sensor for GX-A1+ or GX-HS warning devices, detects hydrogen from leaking fittings of air conditioning and heat pump systems.
Performance features
- High selectivity towards hydrogen
- Small size and low power consumption
- uses a simple circuit
The GX-H2 gas sensor is a sensor for hydrogen (hydrogens) and is used as an accessory for the GX gas detectors in our product range.
The sensor operates in dry rooms. The sensor must not be used in potentially explosive atmospheres.
Scope of delivery
- Gas sensor GX-H2 with 2.5 m sensor cable
- Operating instructions
- Mounting material (screw and dowel)
Performance features
- External sensor for the gas detectors GX-A1 and GX-HS
- Detection of R22, R32, R404a, R407c, R410a, R1234yf, ...
- Climate Fluoro Carbonsare fluorinated refrigerants for air conditioning and refrigeration equipment
The external sensor is suitable for the GX-A1 and GX-HS gas detectors and is connected via an RJ plug connection on the cable. The connection cable of the sensor can be extended. The following minimum cross-sections result depending on the length of the cable: Cable cross-section 3 x 0.75 mm²: maximum length 10 m Cable cross-section 3 x 1.5 mm²: maximum length 20 m
