Design of Industrial-grade sensors for detecting flammable and explosive gasesPortable biogas sensor O2 Gas Leak Detecto
1. Main features
1. Water-proof process from different aspects, IP66/67 is guaranteed
2. The use of silicone rubber ring effectively increased friction between hand and gas detector, thus device is protected from being fallen from hand
3. The plug-in sensor and battery compartment will ensure easier replacement of these parts.
4. Sound, light, vibration 3-mold alarms
5. Product number, calibraiton due date, auto zero function will be displayed after device being activated, this enables users operate and maintain this device more convenient
6. Support unit switch between %LEL---%CH4 for combustible gases and ppm---mg/m3 for toxic gases
7. Support password function
8. Material of enclosure is ABS+PC alloy, anti-static treatment is especially applied
9. Battery can perform good in low temperature environment down to -40°C
10. imported electrochemical sensor, good quality, better performance
