Overview
Enviro Test Construct detector measurement analyzer is a new type of detector for detecting gas leakage from gas pipelines, gas valves, and other possible places. with imported high quality semi-conductor sensor and embedded microcontroller, it has very high sensitivity, excellent man-machine operation interface and various adaptive ability. The housing of the detector is made of high strength engineering plastics and compound anti-slip rubber. It is waterproof, dustproof, and has a good handle.
Features
- Alarm Indicator for concentration exceeds
- Gas detection port carbon monoxide and combustible gas body
- Anti- skid protection chain for preventing
- Use of instruments slip in the process
- Gas concentration concentration display accurate of field gas
- LCD screen display
- Alarm horn sound of 90 Db
- Fixer cover portable detector
- Muffler buttons turn off the sound of the instrument
- Switch key for long press 3s and turn off
