Portable Gas Detectors

Wide range of Portable Gas Detectors supplied across Australia. Single Gas Detectors, Multi-Gas Detectors and Confined Space Detectors. PID Detectors for detection of Volatile Organic Compounds (VOC gases) in ppm concentrations.

Portable Gas Detector

Portable Gas Detectors are worn by the person either working in the area where gas leaks may occur, or for Detection & Monitoring a Confined Space. These Portable Gas Detectors will warn the user by activation of audible, visual and vibrating alarm of a gas hazard, and this will subsequently safe lives by evacuating the hazardous area.. Portable Multi-Gas Detectors are supplied as either diffusion detectors measuring the ambient air for gas and vapours, or with a motorised or manual sampling pump. When it comes to Confined Space Gas Detectors, the Portable Gas Detectors are supplied with either an internal sampling pump, or with an external battery powered pump that clips onto a diffusion type detector. The external sample pump allows the gas detector to be used in both diffusion mode and pump mode in case you need to perform a confined space entry. 

Precision Safety Solutions (PSS) offer a wide range of Portable Gas Detectors across Australia and New Zealand. Most Portable Gas Detectors now come with the option of WiFi or Bluetooth, and you can connect  your gas detector to a grid of multiple detectors, and be warned when a worker is overcome by gas in the plant or work area. PSS is a technical sales and service partner of Portable Gas Detectors for Australia and New Zealand, and this means that we are able to support your equipment after the sale, by providing technical support, service and calibration and maintenance of your gas detectors.

Portable Gas Detectors are mainly classified into three types of Detectors: Single Gas Detectors / Multi-Gas Detectors or Confined Space Multi-Gas Detectors

Single Gas Detectors

Our range of Single Gas Detectors have been designed to be extremely user friendly and robust. They detect a variety of gases that include toxic and VOC gases as well as Oxygen Deficiency and Enriched atmospheres. Single gas detectors are ideal detectors for a large workforce that moves around a lot, or a small workforce where you need to protect yourself from specific dangerous gases. These detectors are equipped with a single target gas sensor, and this means that you may be exposed to other fugitive gases if you don’t have a gas detector for that specific gas.

Single Gas Monitors are available for the following gases:

CO / H2S / CO2 / PH3 / NH3 / CL2 / CLO2 / H2 / O2 / SO2 / HCN / O3 / ETO / NO / NO2 / VOC’s and many more

Multi-Gas Detectors

Multi-Gas Detectors are equipped with a combination of toxic gas, combustible gas and Oxygen sensors. They vary in size and shape, and the number of sensors inside the detectors range between 1 and 6 gases. This ensures that you are protected against a range of possible hazardous gases at the same time, keeping you safe during your work activity.

Multi-Gas Detectors are usually supplied with re-chargeable batteries, and this is due to the sensors requiring power, as well as the demands for portable gas detectors to last more than a 12 hour shift. Carbon Dioxide and Methane gases are detected using Infra-Red sensor technology, which delivers super quick response as well as long sensor life, as they don’t get poisoned by high concentrations of gas.

Precision Safety is an authorised service and repair centre, capable of performing warranty and service repairs on all Portable Gas Detection Instruments. We have highly experienced and qualified service technicians that are well trained and authorised to perform service work.
