|Max. workplace concentration||0.5 ppm|
The ME1250 Gas Sensor is a remote measuring unit for monitoring gas concentration of chloroform. The sensor is used as a leak detector for personal protection and to protect against the anesthetic effect of the gas.
The microprocessor-controlled electronics of the sensor, adapted to the specific properties of the measuring cell, enable fast and reliable signal processing. The measured gas con-centration is transmitted to a Gas Control Panel, which can manage a large number of distributed gas sensors.
Thanks to bus communication, only one cable is required, which can be continued from sensor to sensor. The ME 1250 Gas Sensor is also available with an analogue output signal of 4…20 mA. The measured gas concentration can thereby be processed by other PLC (Programmable Logic Controllers).
The optional relay module expands the ME 1250 Gas Sensor internally with 3 relays for direct switching of signal transmitters without the use of a control panel.
- Automatic zero point calibration
- Active noise reduction on the measurement signal
- Linear measurement signal depending on the gas concentration
- High response sensitivity with short response time
- Selective and reliable measurement with a stable measurement signal and zero point
- Temperature-compensated measurement signal
- Long service life

- The measuring cell can react to larger fluctuations in humidity.
Due to the measuring method, all hydrocarbon compounds are detected. If different gases are to be expected, calibration should be made to the substance for which the sensor has the lowest sensitivity.
