GD4 type multi-parameter sensor for use in mines

One. Overview The product is the latest development of intelligent multi-parameter sensor. It can be widely applied in the presence of flammable, combustible and explosive gas mixtures working environment, continuous detection of methane in the air, oxygen, carbon monoxide, hydrogen sulfide, temperature, humidity, total six parameters, and data remotely via RS485 serial interface transmission. II. Specifications: Item Specification methane (0-5)% Non-scattering infrared principle Oxygen (0 to 25)% of carbon monoxide (0 ~ 1000) × 10-6 hydrogen sulfide (0 ~ 100) × 10-6 temperature (-20 ~ 80) ℃ humidity (0 ~ 100)% RH LCD display intermittent sound and light alarm sound and light alarm operating voltage (9 ~ 24) V output signal (200 ~ 1000) Hz, RS485 Explosion levels Exibd I Mb protection IP54 Dimensions Shape 245 × 125 × 55mm Weight 0.8kg III.
