Mine oxygen sensor GYH25 Jining Branch-company supplies GYH25 mine wall-mounted oxygen sensor oxygen sensor GYH25 mining products GYH25 mine with a brief description of the oxygen sensor is intrinsically safe equipment. The instrument applies to all workplaces in the coal mine to measure the concentration of oxygen in the air. Instrument calibration function with infrared remote control; has overrun sound and light alarm. Oxygen concentration sensor signal with remote function, through frequency, current or digital signal transmission. Environmental adaptability, easy installation, can be used with other domestic coal and non-coal mine monitoring system compatible for use.
