Designed to meet with tough industrial requirements, the Smart-Detector allow monitoring toxic and flammable contents in harsh environments and classified areas.
They offer a 4-digit back-light display and 5 mode status LED for the gas concentration reading.
Ideal in harsh environments, the Smart-Detector feature non intrusive calibration for an accurate and easy adjustment via Hall-effect switches, without opening the instrument and declassifying the area.
The detectors is IP65 protected and SIL2 Hardware tested (not certified) and provides a simple concept to replace sensors. As an option the gas detectors is also available without a display.
