GJC4 Low Concentration Methane Sensor

GJC4 Low Concentration Methane Sensor Introduction

GJC4 LowConcentration Methane Sensor and domestic various types of detection system and gas lock off all, wind power, suitable for gas coal dust explosion dangerous in coal mine underground mining working face, mechanical and electronic chamber, such as return air roadway place regular use. Low concentration of methane sensor for monitoring the concentration of methane in mine change and development of special instrument.
GJC4 Low Concentration Methane Sensor can continuous downhole automatically to methane concentration into a standard electrical signal transmission device context.
Low concentration of methane sensor with local display the methane density, overrun acousto-optic alarm, power function and high concentration power-off protection carrier catalytic element, and other functions.
