Single Gas Detector


The IX176 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 has a high-quality sensor, and uses natural diffusion as the method for detection. It has high sensitivity and reproducibility. The detector uses an embedded MCU controller, and is easy to operate. The shell has special high strength material and anti-slip rubber, and is water-proof, explosion-proof and dust-proof. The alarms are visual, and audible with vibration.

Can store up to 2,000 readings on the internal memory.

Data transfer software and USB cable included.
