Portable Infrared CO2 gas detector CRG5H
Qualifications: Coal Mine Safety Certificate
Explosion-proof Certificate
Inspection Certification
Applications:
Infrared CO2 detector is an intrinsically safe and explosion-proof instrument and is designed to deter CO2 concentration in ambient air continuously and rapidly.
It adopts NDIR infrared technology with high accuracy and fast response. The measuring range of CO2 gas is 0-5.0%.
Despite its compact size, the Infrared CO2 detector includes features usually found only in larger multi-gas monitors including a large, OLED display, internal audible/visual alarms and simple push-button operation.
The monitor continuously displays ambient CO2 gas readings and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. Infrared CO2 detector also has a peak/hold feature to show the highest reading during a shift and includes a special flip-cap calibration adapter for quick and simple calibration. It is covered by a two-year warranty from the date of manufacture.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the combustible gas.
| Feature | Benefit |
| Sensor lifetime | 5 years, NDIR infrared sensor |
| 2-year warranty | Lowers the overall cost of ownership by providing a full 24 months of warranty coverage. |
| Display | High brightness backlight display |
| Calibration | The user’s own can calibrate the detector by operating on it |
| Flip-cap calibration feature | Infrared CO2 detector has a unique, built in calibration adapter to make calibration easy and eliminates the need to search for a calibration cup. |
| OLED display | Provides continuous display of the actual concentration of combustible gas in the ambient environment as well as remaining battery life. |
| Adjustable low and high alarm setpoints | The user can configure single Infrared CO2 detector to suit a number of different applications. |
| High visibility case | From a distance, it’s color makes it easy for Safety Professionals to verify that workers are protected. |
| 5 second delay shut-off protection | Infrared CO2 detector cannot be accidentally shut off since the on/off button must be depressed for five continuous seconds. |
