Description
Overview
GAOTek portable ammonia gas detector can detect combustible gas, O2 and two other types of 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 damaging the relevant equipment.
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
