Description
TXgard-Plus is a flameproof toxic and oxygen gas detector suitable for use in zone 1 or 2 hazardous areas. It is designed to detect toxic gases and oxygen using a range of electrochemical sensors.
A local display and magnetically operated switches allow non-intrusive one-man calibration without a hot work permit.
Powered by 24 VDC (nominally) TXgard Plus provides a 4...20 mA signal (sink or source) proportional to the gas concentration and can also be fitted with optional alarm and fault relays.
