TXISP-H2S-SIDE-Sira-100 TXgard-IS+ Toxic Gas Detector with Display, Hydrogen Sulphide 0-100 ppm by Crowcon
TXgard-IS+ is a Intrinsically Safe (I.S.) toxic and oxygen gas detector with local LCD display. A wide choice of sensors are available for use in a variety of applications.
Features:
Non-intrusive calibration
- Calibration can be performed locally without the need for hot work permits
- Local display and buttons enable calibration without opening the junction box
Flexible output options
- A two-wire 4-20mA signal is provided
- The output can be forced up without applying gas to enable simple checking of control systems and alarms.
Rugged and reliable
- Constructed using highly durable GRP to provide good impact resistance
- Ingress protection to IP65 as standard, IP66 with accessory
- IEC61508 SIL compliant
