TRP-01-NU-Z-IR Triple Plus + IR Portable 4-Gas Detector, IR CH4 % LEL, O2, H2S, CO Pumped by Crowcon

Incorporating infrared detection technology, the Triple Plus+ IR extends the capability of the Triple Plus+ allowing extended life detection of hydrocarbons and carbon dioxide.

IR sensors have high resistance to interference or inhibition by other gases and are suitable for both high gas concentrations and use in inert (oxygen free) backgrounds.

The unique design of the Crowcon IR sensor module used in Triple Plus+ IR allows measurement of hydrocarbons at both % LEL and % vol. ranges making this instrument ideal for tank and line purging applications within oil and gas and industrial applications.

Clear and unambiguous

  • Piercing 85dB at 1m
  • Vivid LED alarms with top visibility
  • Confidence blip, low battery and TWA warnings
  • Timed datalogging with 100 hour capacity
  • Gives you confidence in the status of your Triple Plus+, and the environment you’re working in

Simple to customise

  • Wide range of electrochemical oxygen and toxic gas sensors
  • Available for diffusion, manual aspiration or pumped sampling
  • Interchangeable sensor modules
  • Comprehensive datalogging with site and user names
  • Allows you to create your optimum 4 gas Triple Plus+


  • Triax casing will not crack or shatter when dropped
  • Unique internal design will resist the harshest treatment
  • Full buoyancy
  • System integrity and operation assured
  • Makes recovery from water possible

Easy to maintain

  • Simple Windows Software interface
  • QuickCal, rapid calibration
  • User menus allow calibration with or without connecting to a PC

IR Option

  • No poisoning effects
  • Long life sensor and no burnout
  • % vol. measurement for purging applications
  • % LEL measurement in air or inert backgrounds
  • Single or dual range measurement
  • IR CO2 detection, 0–5%
  • Works well where catalytic pellistors would perform poorly
  • Reduced cost of ownership
  • Offers flexibility
