产品描述: |
A warning system for combustible gases in a small package.
Common warning instruments for combustible gases are cumbersome, heavy and large. Not so with the Ex plus, one of the lightest instruments on the market.
Compur Ex plus continuously measures the actual concentrations of combustible gases and vapors. The measured value is displayed on an easy-to-read LCD display in '% LEL' (percent Lower Explosion Limit). If one of the two freely adjustable alarm thresholds is exceeded, it gives visual and audible warnings within seconds. The two alarm thresholds are identified by different alarm tones.
With its rugged ABS housing, it withstands even the harshest industrial environment.
The sensor is a field-proven catalytic combustion sensor (pellistor).
Compur provides the sensors pre- calibrated for the gas or vapor to be measured. For substances which make recalibration difficult, the sensor will be calibrated with an additional reference gas. The reference gas and the reference factor are printed on the sensor label. This facilitates the recalibration of the instrument in the field.
A simple push of a button gives access to the gas calibration- or the alarm level adjustment menu, without opening the instrument. The sensor bridge voltage can even be displayed on the LCD display - an excellent indication of the sensor condition.
The Ex plus is available with two different battery packs: the mini-version providing four hours operation time, or the long-time monitoring version providing up to fifteen hours operation time. The explosion proof rechargeable battery packs can easily be changed in seconds, no tools needed. This allows users to convert the mini-detector into a long-time monitor even in hazardous areas.
