Detailed Description

CJYB4/25 Methane - oxygen and alarming device CJYB4/25 methane - oxygen and alarming device is imported pressure compensation type oxygen sensor and thermal catalytic methane sensor (commonly known as black and white) component of the intelligent portable instrument. Instrument applies to the coal mine's workplace measuring the methane concentration in air and oxygen concentration. Instrument to measure the oxygen density has nothing to do with well depth, without difference amendment. Instrument with sound and light alarm function; Super range automatic shutdown function; The battery voltage display function; Under voltage automatic shutdown function; Automatic charging and battery protection function. Measuring range: oxygen O2 methane (0.0 ~ 25.0) % (0.00 ~ 4.00) % CH4 Basic error: methane CH4 (0.00 ~ 1.00) %, plus or minus 0.10% CH4 CH4 (1.00 ~ 3.00) %, the true value of plus or minus 10% CH4 (3.00 ~ 4.00) %, plus or minus 0.30% CH4 When oxygen O2 (0.0 ~ 5.0) %, plus or minus 0.5% O2 O2 (5.0 ~ 25.0) %, plus or minus 3% FS Warning: sound and light alarm Display way: four LED rotating display methane and oxygen concentration. Electricity source, use 3.7 V lithium ion batteries Explosion-proof type: mining flameproof and intrinsically safe Explosion-proof marks: ExibdI Other features: imported gas sensitive components
