The First Responder from GMI is a combustible gas indicator designed for emergency response technicians in the gas industry.
The First Responder detects flammable gas at PPM, LEL and % Vol levels with the addition of carbon monoxide for internal atmosphere monitoring.
An optional external range diffusion probe with high speed semiconductor sensor enables rapid response in detecting small fitting leaks. 性能:
