Toxic gas detector product introduction
Toxic gas detector is used to continuously monitor the concentration of toxic and harmful gases and explosive gases in the environment in the coal mine and roadway.Toxic gas detector is suitable for measuring and alarming the concentration of carbon monoxide, oxygen, and nitrogen dioxide gas in underground coal mine operating environments.It has functions such as date, time, sound and light alarm.The measuring device has the advantages of simple operation, easy portability, accurate and reliable.
a.Temperature: 0℃～+40℃
b.Relative humidity: ≤98% (+25℃)
c.Atmospheric pressure: 80~110kPa
d.Wind speed: ≤8m/s
e.No significant vibration or impact
f.In dangerous places with explosive gas mixtures.
| Measure gas | Carbon monoxide, oxygen, nitrogen dioxide |
| Measurement principle | Electrochemical principles (CO, O2, NO2) |
| Measurement range | CO：（0~1000）×10-6 O2：（0.0~25.0）% NO2：（0.0~100）×10-6 |
| Basic error | CO：（0~20）×10-6：±2×10-6 （20~100）×10-6：±4×10-6 (100~500): ±5% of the true value (500~1000 ): ±6% of truth value O₂ (0.0~5.0)% O₂: ±5% O₂ (>5.0~25.0)% O₂: ±3% O₂ FS NO₂：（0~20.0）×10-6：±2.5×10-6 |
| Alarm point and error | The alarm value can be set at will, the following is the default alarm value CO: alarm point 24×10-6, alarm error ±1×10-6 O₂: alarm point 18.0%, alarm error ±0.3%O₂ NO₂: alarm point 5.0×10-6, alarm error ±1×10-6 |
| Response time | CO: No more than 45 seconds O₂: No more than 35 seconds NO₂: No more than 45 seconds |
| Alarm sound level intensity | Not less than 80dB (1 meter away from the buzzer) |
| Light alarm intensity | Not less than 20 meters (dark) |
| Sensor life | 1 year |
| Continuous battery working time | >12 hours (non-alarm status) |
| Appearance and size | 127mm×67mmx43mm/500g |
| Explosion-proof form | Intrinsic security for mining |
