The SPID is a Stationary Photo Ionization Detector for permanent monitoring and measurement of a broad range of total volatile organic compounds (VOC), which can be dangerous from both a poisoning and explosive perspective. Total VOC’s are detected using PID (Photo Ionization Detection) technology. A hollow cathode lamp (10.6 eV) will be used as ionization source. This lamp provides a high stable light output and a guarantied life time for more than 5000 hours (typical up to 10000 hours).

The SPID has a built-in automatic calibration with self-cleaning feature and the internal pump working continuously. It has a number of user selectable features, which define its operation. The detector provides an analog (4-20mA) output** to represent the linearized and compensated concentration value in different scaling and digital (RS485-MODBUS) output which supports reading measurements and diagnostic results, remote calibration and configuration. The SPID is equipped with a graphical back-lighted display and high brightness Led’s for normal operations, failures and alarm conditions. The intuitive graphical menu guide and a non – intrusive magnetic key interface make it easy to use. An explosion-proof stainless steel enclosure makes the SPID ideal for use in hazardous environments.
