One-point Type Gas Alarm SystemNV-100H
- Gas Detected
- Combustible gas (LPG, methane, etc.)
- Detection Principle
- Hot wire semiconductor
- Detection Range
- As per specification
- Concentration Indicator
- LCD bar-graph meter with backlight
Compact one-point type gas alarm system for combustible gases (High sensitivity).
- Full maintenance functions with very easy zero and span adjustment.
- Proven reliability with years of experience – COSMOS gas sensors have a small zero drift, a small sensitivity decrease, and a long life.
- Zero suppression function cancels slight fluctuations of the reading due to environmental change.
- Compact Indicator/Alarm unit – W113 x H204 x D71.5 mm, Approx. 1.5kg.
- Battery provides backup power in case of a power failure, allowing continuous monitoring over 60 minutes after the failure. (option)
