OLCT 10N Fixed Gas Detection
Brand: OldhamThe OLCT 10N is a digital gas detector designed for detection of the most common gases in commercial and light industrial applications.
Intended for use in combination with the MX 43, the OLCT 10N provides a fast and accurate response. Up to 32 detectors can be connected on the same digital line or distributed on 8 lines.
All transmitter information is received by the controller in less than 1 second.
Non-intrusive operator interface requires only a simple magnetic wand and allows one man calibration without opening the enclosure, and calibration information, such as span reserve, is stored in the MX43.
The OLCT 10N is IP65 and ATEX 3 GD certified, for use in ATEX 2 and 22 zones, and is water- and dustproof.
Features- Detection of combustible gases, toxic gases or oxygen
- Digital technology
