A versatile, toxic, and oxygen gas detector with LCD display and non-intrusive calibration. Available for detecting a wide range of gases, the Crowcon TXgard-IS+ is Intrinsically Safe, ATEX and IECEx certified for use in Zone 0, 1 or 2 hazardous areas, and UL and cUL certified for use in Division 1 or 2 hazardous areas.

The TXgard-IS+ uses an electrochemical sensor within a reusable bayonet housing. Supplied with a carbon-loaded nylon junction box, which contains the amplifier/transmitter to provide a 2-wire 4 to 20mA output (M20 cable gland entry). The LCD has a 2 x 16 character display with menu functions accessed via a keypad.

Features

Non-intrusive calibration

  • Calibration can be performed locally without hot work permits and minimises operational downtime.
  • Local display and buttons enable calibration without opening the junction box.

Flexible output options

  • 4-20mA current sink – works with a wide selection of control panels.
  • Two-wire format.

Rugged and reliable

  • Made from tough carbon-loaded nylon.
  • Ingress protection to IP65 as standard.

Low cost of ownership

  • Non-intrusive one-person calibration – easy to operate and maintain.
  • Long-life sensors – minimise interruptions to on-site activity.
  • Simple parts replacement.

Wide range of sensors

  • An extensive range of electrochemical sensors for toxic gases and oxygen.
