The Crowcon TXgard-IS+ gas detector is easy to calibrate. Maintenance and operation are simple and the long life sensors keep disruption to site to a minimum.

Crowcon TXgard-IS+ has an ingress protection to IP65 as a standard.

Crowcon TXgard-IS+ Fixed Gas Detector – Key Features

Carbon Monoxide Gas Detectors

Intrinsically Safe (I.S.) Toxic & Oxygen Gas Detector

  • Robust Construction – Crowcon TXgard-IS+ is constructed from tough carbon loaded nylon and an IP65 rating as standard
  • Flexible Options – The TXgard-IS+ is available in 2 or 3 wire formats with a 40-20mA current sink or source. Relays for alarm and fault are also options
  • Low Ownership Costs – Sensors are long life with simple part replacement making the gas detector easy to operate and maintain
  • Calibration – The TXgard-IS+ can be calibrated with ease and boasts local display and buttons so the junction box doesn’t need to be opened. Non-intrusive one man calibration can be performed locally without the need for hot work permits
  • Range of Sensors – This gas detector can be tailored to meet the user’s needs with a choice of catalytic beads for a wide selection of flammable gases and vapours and an extensive range of electrochemical sensors for toxic gases and oxygen

Crowcon TXgard-IS+ Bump Testing And Calibration

Routine bump testing is recommended for the range of Crowcon fixed gas detectors prior to each use. Bump testing is a brief application of a gas to the sensor to invoke a prescribed reaction, ensuring the gas detector reacts as expected.

Bump testing provides a quick, easy and direct method of verifying gas detectors are performing as required and takes a lot less time than ‘zeroing’ the device. 

The bump test is widely accepted as a suitable method of testing gas detection equipment.
