Introduction of DM100 CH4 CO O2 H2S Four In One Gas Detector
Compact portable gas detector with a large LCD, it can monitor CO, H2S, O2 and combustible gas simultaneously. The instrument features two instant alarms with audio/visual and vibratory indicators, rechargeable battery, and simple use.
1. Astigmatic design is applied to rugged surroundings;
2. Continuously gas concentration and composition LCD real-time display;
3. Rechargeable lithium battery (continuous working period can be 16~18 hours);
4. Concentration units ppm and mg/m3 can be switched
5. Built-in vibration alarm which is applied for noisy environment;
6. Two stage alarm threshold: the low alarm and high alarm point can be adjusted based on actual needs;
7. Simple automatic calibration program and plug-in replaceable sensor;
8. Fully functional self-testing: sensor, integrity of battery and circuit, acoustic & visual & vibration three-stage alarm;
9. Small figure and light weight;
10. Password protection capability: only the authorized user can modify the preset parameter.
