Application:
JFY-4B Multi-Function Ventilation Meter is an intrinsically safe and explosion-proof instrument, especially designed to measure temperature, differential pressure, wind speed and concentration of methane gas. It is used at the ventilation resistance, HVAC and pipeline inspection mainly. The instrument had been calibrated precisely before they left the factory. As long as you use correctly, the instrument can work stably for a long time.
