TXgard-IS+ is a Intrinsically Safe (I.S.) toxic and oxygen gas detector with local LCD display. A very wide choice of sensors are available for use in a variety of applications. TXgard-IS+ is ATEX certified for use in Zone 0,1 or 2 hazardous areas and also UL and cUL certified for use in Division 1 or 2 hazardous areas.
Non-intrusive calibration
• - Calibration can be performed locally without the need for hot work permits – minimises operational down-time
• - 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
• - 2 wire format
Rugged and reliable
• - Made from tough carbon loaded nylon
• - Ingress protection to IP65 as standard
Low cost of ownership
• - Non-intrusive one man calibration – easy to operate and maintain
• - Long life sensors – keeps interuption to on-site activity to a minimum
• - Simple parts replacement
Wide range of sensors
• - Extensive range of electrochemical sensors for toxic gases and oxygen
