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 8-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 are IP 65 protected (optional IP67) and complying with SIL3 SW and SIL2 HW. As an option, the sensor is available with dual-head concept and in stainless steel construction.
