About this Item：

Portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed.The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate. The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof. 
Features：

Industrial-grade sensor, high precision, real data, strong stability, real-time detection.

Triple alarm mode (sound, light, vibration) is not easy to ignore, high security, high and low

alarm value can be set free.

7v rechargeable lithium battery, battery capacity 1500MA, charging time is less than five

hours, continuous work for more than ten hours (gas detection is not less than 7 hours).
