Description
Overview
GAOTek Gas Detector for CO/H2S/O2/LEL detects concentration of four gases and supports two instant alarms with audio/visual and vibratory indicators.
Key Features
- Astigmatic design is applied to rugged surroundings;
- Continuously gas concentration and composition LCD real-time display;
- Rechargeable lithium battery (continuous working period can be 16~18 hours
- Concentration units ppm and mg/m3 can be switched
- Built-in vibration alarm which is applied for noisy environment;
- Two stage alarm threshold: the low alarm and high alarm point can be adjusted based on actual needs;
- Simple automatic calibration program and plug-in replaceable sensor;
- Fully functional self-testing: sensor, integrity of battery and circuit, acoustic & visual & vibration
three-stage alarm; - Small figure and light weight;
- Password protection capability: only the authorized user can modify the preset parameter.
