SD-1 Smart Transmitter Detector

SD-1 Smart Transmitter Detector

Our SD-1 line of smart transmitters feature state-of-the-art gas detectors with durable flameproof enclosure, maximum safety, especially in hydrogen/ acethylene atmospheres. A simple magnetic control key is placed over clear marked positions on the surface plate to test and adjust the instrument without opening the transmitter in situations with danger of explosion. This “single-man-calibration” is already in use and applicable with other Control Equipment gas detectors for easy maintenance.
