Crowcon's
TXgard line of remote gas detectors provide a wide variety of configuration
options for all gas detection applications.
The
Flamgard and TXgard ‘Plus’
range of gas leakage detectors offers reliable detection of
flammable, toxic or oxygen gases with a local display and optional
relays. Three models are available to suit all requirements:
Flamgard Plus Gas Detector...
This is a
Flameproof combustible gas detector that uses a pellistor-based sensor to
detect explosive levels of hydrocarbons, hydrogen and other combustible
gases. Flamgard Plus can also detect vapors, including leaded
gasoline and aviation fuel.
TXgard Plus Gas Detector...
This is a flameproof
toxic and oxygen gas detector that has a choice of sensors for a wide
variety of applications. Features local LED display and non-intrusive
calibration.
TXgard-IS+ Gas Detector...
This is an Intrinsically
Safe (IS) toxic and oxygen gas detector. TXgard-IS+ is designed to detect a
wide range of toxic gases when fitted with the appropriate sensor.
BPA Choice Manufacturer...
TXgard gas detection equipment is manufactured by Crowcon, a
worldwide leader of gas detection solutions for over 35 years.
Crowcon gas leak detection instruments offer customers innovation
design, accurate and dependable readings with low maintenance, cost
effective operation. In our opinion, Crowcon makes the most reliable
and easy to use gas monitors. After extensive gas detection product research, Crowcon was an obvious
choice to supply superior gas detection equipment.
