Fixed Gas Detection / Fixed Gas Detectors


PSS is a specialist supplier of a wide range of Fixed Gas Detectors or Permanent Installed Gas Detectors in Australia and New Zealand. We supply stand-alone gas detectors and monitors or detectors and controllers integrated into existing plant PLC and control systems, Precision Safety Solutions offers made-to-measure solutions to meet your requirements and budget for any Fixed Gas Detection requirements.

When personnel monitoring is not available or suitable, permanently installed detection systems (detectors and controllers) are used for continuous monitoring. These fixed gas detectors are strategically positioned to optimise detection coverage and can initiate a variety of safety related actions in the event of a gas leak.

Precision Safety offers a range of fixed gas detectors for the detection of Toxic, Combustible gases as well as Oxygen Deficiency/Enrichment. Examples of appropriate actions are the activation of audible/visual alarms or ventilation/ extraction systems and shutting down of plant equipment.

PSS not only supplies the permanent installed gas detection equipment, we also arrange installation by suitable qualified trades people. After the installation Precision Safety performs the commissioning of the fixed gas detectors and offer on-site scheduled calibration and service, as this ensures they are always in great working condition..
