SD-805 Series Smart Transmitter / Infrared Gas Detector

With a visual display the Model SD-805 series smart transmitter/detector heads are state of the art instruments housed in a flameproof enclosure. Calibration of the instrument is able to be carried out with a simple magnetic control key by placing it over clear marked positions on the surface plate.  It is ideal for Intrinsically Safe Applications.

A magnetic control key is placed over clear marked positions on the surface plate of the SD-805 to test and adjust the instrument without opening the transmitter / detector head. Two different detection principles are provided with the SD-805 series which enable you to select the most suitable principle according to the detection gas, range and application for use. Especially, the Model SD-805RI can detect combustible gases (CH4 and i-C4H10) with 0 – 100 vol% F.S. in inert gas base.
