1. It’s a comprehensive tester to gas drainage pump and pipe.
2. Measure and display pipe CH4/CO2/CO/O2 concentration, negative pressure, differential pressure, absolute pressure and pump absolute pressure, rotational speed, voltage, current, power, efficiency in real time. For water ring vacuum pump, measure its water pressure, inlet water temperature, outgassing temperature, temperature and humidity in pump house.
3. Cooperating with self-developed flow testing device, it can get accurate flow value fast.
4. It’s significant to gas drainage system safety inspection and maintenance, gas accident prevention, productivity improve, environment protect, resource utilization.
