Gas Sampling System For Hard To Access Locations

The TOCSIN 750 2-Wire addressable gas sampling system allows you to provide gas detection in areas which may otherwise be difficult to access.

Typical examples could include:

  • Clean Rooms: 750 gas sampling systems combined with IGD’s through wall sample points are the perfect option for clean rooms.
  • High Level gas Detection: No need to fit gas detection into high roof bays where access would be difficult. 2-wire 750 series sampling systems can be easily fitted at ground level with tubing running to the high level roof space.
  • Pits and Sumps: These are usually inhospitable places for gas detectors. IGD’s 750 2-wire series sampling system, allows the detection module to be conveniently located for service with tubing running into the pit, sump or drain.

Furthermore the 750 2-wire addressable sampling system incorporates the latest in piezo pump technology, with virtually no moving parts, no valves, no pump seals, resulting in high reliability and low maintenance. A zero port is provided with active filtration to allow the module to periodically zero or calibrate itself. This allows reduced detection limits as the detector has less zero drift.
