Iso9001 Certified Portable Multi Gas Analyzer For Ex H2S O2 Co
Production Introduction:
Portable Multi Gas Detector with a large LCD. It can monitor CO, H2S, O2 and combustible gas simultaneously. The instrument with audio/visual and vibratory indicators, rechargeable battery, and simple use.
It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers' life and avoid damage on the relevant equipments.
Main Features:
1. Advanced MCU control with low power consumption
2. Advanced integrated circuit technology, embedded microcomputer control
3. Adjustable low and high alarm level
4. Adjustable calibrating level
5. High concentration protection for combustible gas
6. Self test for the combustible gas sensor
