Overview
Enviro Forest portable multi gas detector could detect combustible gas, O2 and other two types toxic gases continuously and simultaneously. 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.
Features
- Advanced MCU control with low power consumption
- Adjustable low and high alarm level
- Adjustable calibrating level
- High concentration protection for combustible gas
- Self-test for the combustible gas sensor
- Low battery indication
- Replaceable sensor module
- Self-adjustment function
- Visual and audible alarm with vibration
- STEL and TWA alarming for toxic gases
- Advanced self-examination and self-renovation function
- Password management to avoid wrong operation
- Explosive proof housing
