Description
Overview
GAOTek laser sensor methane gas detector transmits an infrared laser to the monitoring point which can quickly measure the air mass concentration between the detection point and the telemeter. The telemeter can accurately detect the methane concentration value of the searched location in real time and display and store it. When the alarm value is exceeded, it will give an audible and visual alarm so that the personnel can make follow-up treatment.
Features
- Emits a visible red laser to the monitoring point at the same time
- Non-contact detection
- Suitable for areas that are difficult for people to access or high above the ground
- Suitable for explosion-proof places
- More accurate and efficient
- Compact design, easy to carry
- Life span of up to ten years
