Pellistor Special Gases Detector in IP55 Box

G701P-2

The detector is equipped with a head with a Pellistor sensitive element that measures the concentration of the explosive gas on the LEL (Lower Explosive Limit) scale. With this type of sensitive element, the correct reading is ensured, even in bad environmental conditions. The detector is delivered with a pre-alarm threshold of 15% and an alarm threshold of 30% of the LEL. Optionally, an interface with Android App and a PC software are available, which allow the field testing of the detector, and the modification of detection thresholds, alarm filters, addressing, full scale, etc. The detector is equipped with an ADFT IP55 certified dust-proof metal box, housing both the communication electronics and the sensor element, positioned in the lower part, and protected by a special stainless-steel mesh.

  • Multiple communication modules for all kinds of applications
