GasPlus-IR® Transmitter

The Model 4688-IR is a rugged, reliable solution for detecting hydrocarbon-based combustible gases. Designed with extensive user input, the instrument is extremely flexible, easy to use, and easy to maintain.

The GasPlus-IR is suitable for most applications where catalytic bead detectors are currently used - as well as some applications where catalytic sensors won’t work.

IR technology provides numerous advantages that may be benificial for your application’s conditions:

• Reduced maintenance (no span calibration required).
• No saturation from high gas concentrations
• No oxygen required for operation
• Continuous sensor fault monitoring
• Sensor lifetime not reduced by exposure to gas
• Rapid speed of response
• Minimal temperature and humidity effects

Features:

• Low Maintenance
• No span calibration required
• Zero adjustment a quick, non-intrusive procedure
• Rugged Design with nickel plated optics component protection
• Multiple Output Choices 4-20mA and RS/485 (Modbus protocol) outputs. Relays with user adjustable set/reset points, and time delays are available as an option.
• User adjustable relays available as an option)
• Low Cost of Ownership
