Other features:
- Adopting an integrated explosion-proof design
- Adopting explosion-proof processing buttons
- Standard oil filtration device to prevent oil contamination in the sensing unit
- Online dual hydrogen purity monitoring with pressure, improving data reliability
- Explosion proof units can be installed independently or equipped with sampling racks
- Hydrogen purity and humidity measured with pressure, resulting in hydrogen waste due to less emptying measurement
