Product Introduction of JFY-2 Mine Ventilation Multi-Parameter Measuring Instrument
The JFY-2 Mine Ventilation Multi-Parameter Measuring Instrument is a precision handheld portable device capable of simultaneously measuring underground pressure, relative pressure, wind speed, temperature, and humidity. It provides an effective measurement tool for pressure balance fire prevention, scientific management of mine ventilation, and determining mine ventilation network pressure-energy diagrams.
The explosion-proof type of the JFY-2 Mine Ventilation Parameter Instrument is intrinsically safe for mining use, with an explosion-proof mark of ExibI, making it suitable for coal mine underground applications.
