Crowcon Triple Plus+ high-end Gas detector, 4-gas measurement

Máy đo khí Crowcon Triple Plus+
Máy đo khí Crowcon Triple Plus+

Crowcon Triple Plus can optionally measure 4 gases simultaneously in the following category:

LEL, H2S, CO, O2, SO2, Cl2, NO2, NH3, H2, HCN, HCl, PH3, F2, CH4, ClO2, HF, ETO, NO, CO2

Crowcon Triple Plus+ is the latest generation of the Triple series for measuring oxygen, flammable gases and toxic gases. With more than 90,000 devices sold into oil and gas, chemical companies … worldwide, the combination of durability, reliability and ease of use and flexibility of sensors sets the standard for portable Gas detectors.

The current Triple Plus+ built on root includes special TECHNOLOGY LIBRA lithium-ion battery technology and IR infrared sensor option for flammable gas and Carbon dioxide measurements.

In essence, Triple Plus+ provides premium conditions for detection and safety with teams and management including a selection of adjustment elements for flammable gases (so a device can be used in some areas) and documents explaining the use name and site name selected from the file reconfigured on the device.

  • IR Infrared Sensor Options
  • IR infrared sensors have high resistance to interference or restraint by other gases and are suitable for both high gas concentrations and use with inert gases (without oxygen) against a background where the touch sensors will work very poorly.
  • The special design of Crowcon‘s IR infrared sensor used in Triple Plus+ IR allows measurement of hydrocarbons at both %LEL and % volume ranges making it ideal for tank and tank applications.
  • Unaffected by poisoning – work well where the catalyst sensor works poorly
  • The age of the sensor is long and not burnt – reducing the cost of ownership
  • Measure with units % volume for cleaning applications – flexible supply
  • Measured with %Lel units in the air or basic
  • Single-band or double-band measurement
  • CO2 detection with measuring range 0~5% vol



  • 85dB audio at a distance of 1m – gives you confidence in the state of where Triple Plus+ works
  • Lively led warning lights with the view position above the top
  • Trust alerts, low battery and TWA
  • Marked data recording time with capacity over 100 hours

Easy customization

  • Wide range of electrolytizing sensors and toxic gas sensors – Allows you to create a 4-gas option
