SD-805RID-HEX SD-805 Smart Transmitter/Gas Detector for %LEL Hexane by RKI Instruments
The model SD-805 series Smart Transmitter/detector heads are state of the art instruments housed in a flameproof enclosure.
A simple magnetic control key is placed over clear marked positions on the surface plate to test and adjust the instrumentwithout opening the transmitter/detector head.
Two different detection princples are provided with SD-805 series which enables you to select the most suitable principle according to your detection gas, range and application for use. Especially the model SD-805RI can detect combustible gases (CH4 and i-C4H10) with 0-100% volume F.S. in inert gas base.
Dual alarm contacts and trouble alarm contact are provided for activation of external buzzer or alarm light. Powered by 24 VDC, the unit has a 4-20mA output for communication to outside controllers, for external readouts or alarming devices.
An extensive range of accessories supplied by RKI rounds up Model SD-805 series
Features:
- For combustible and toxic gases
- Longlife RKI sensors
- Dual alarm contacts
- 4-20mA linear output
- Automatic zero correction function, self-diagnosis
- Explosion proof housing, IP65 ingress class
- ATEX and MED approved (Wheelmark)
*Please note we can only ship RKI products to customers within the United States
