Electrochemical Ammonia Detector in IP55 Box

G708H-2

The detector is equipped with an electrochemical cell head that measures the toxic gas concentration on the ppm (parts per million) scale or the volume percentage of the oxygen in the air. The detector is delivered with a pre-alarm threshold of 100 ppm and an alarm threshold of 200 ppm. The oxygen versions are with a pre-alarm threshold of 24% vol., and an alarm threshold of 27% vol. 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.
