SD-705RID Smart Transmitter With Alarm Relay/Infrared Gas Detector for %LEL Isobutane by RKI Instruments

This is a flame proof gas detectorfor LEL level detection of methane and many other hydrocarbons. This detector uses the non-dispersive infrared absorption (NDIR) detection method, which is free from interferences from H2, most non hydrocarbon refrigerants, and most other gases or vapors. The sensor also is not poisoned or influenced by silicon vapors, or corrosive vapors, which typically can destroy sensors from other detection methods.

The SD-705 is compact and easy to install and operate. The adjustment control is a magnetic wand that is easy to use by placing it onto the glass window of the gas detector. Gas concentration is read through window, and adjustable dual alarm contacts 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 additional external readouts or alarming devices.

Features:

  • Dual alarm contacts provided
  • Simple adjustment with magnetic control key
  • Non-dispersive infrared absorption (NDIR) method applied
  • Remote detector connection capability
  • Simple one man calibration
  • Self-diagnostic by internal microprocessor
  • Stable reading and good gas selection by NDIR
  • Free from interference of inert gas and H2 etc
  • Back-lit LCD provided
  • Peakhold function provided (option)

*Please note we can only ship RKI products to customers within the United States
