NB. The price shown is for a PS500 gas detector with a Drycell Battery + Pump + Datalogging. Selected gas sensor options are available in the dropdown. There are over 15 plug-and-play smart sensors to choose from. For full options and prices please call your local Cuthbertson Laird Group office.

The GMI PS500 is used for confined space applications, for example, in sewers, underground piping or within tanks and other personal monitoring applications.Its high intensity audible and bright visual alarms provide early warning of dangerous gas levels. The instrument is operated by two buttons providing the user with a simple to use gas detector.

The PS500 can be tailored to detect up to five gases with its toxic and catalytic sensors, photo ionisation detectors and infrared capabilities. ‘Plug and Play’ option allows the customer to ‘plug in’ a new board with a different gas range.

With an expansive list of gases that can be detected for fast response times, a high level of accuracy and audible and visual alarms; the PS500 provides unrivalled protection against the potential exposure to flammable and toxic gases, along with threats of oxygen enrichment or deficiency.

The PS500 is particularly useful in noisy environments, featuring a very loud (95dBA) penetrating and distinctive audible alarm together with high visibility large area visual alarm. Pump, diffusion or both together, allowing pumped sample for pre-entry checking and diffusion in confined space working, thus maximising battery life. A robust, moulded, rubberised casing guaranteeing Hi-Impact resistance, the PS500 can be used in the most demanding environments.


Over 15 plug-and-play smart sensors to choose from.
Wide range of VOC’s with 2 different PID sensors.
Flexible configuration to suit your specification.
Piercing 95 dB audible plus 360-degree high visibility light bar.
On-board datalogging for calibration certificates, data management and event logging.
High impact rubberised case.
Low cost of ownership.

Up to five gases can be monitored from the following list:

0 to 100% LEL Hydrocarbons.
0 to 25% Oxygen (O2).
0 to 100 ppm Hydrogen Sulphide (H2S).
0 to 1000 ppm Carbon Monoxide (CO).
Dual Sensor - Hydrogen Sulphide (H2S) / Carbon Monoxide (CO).
0 to 30 ppm Sulphur Dioxide (SO2).
0 to 100 ppm Sulphur Dioxide (SO2).
0 to 10 ppm Chlorine (Cl2).
0 to 20 ppm Nitrogen Dioxide (NO2).

0 to 300 ppm Nitric Oxide (NO).
0 to 5% Carbon Dioxide (CO2).
0 to 100 ppm Phosphine* (PH3).
0 to 20 ppm Benzene* (C6H6).
Volatile Organic Compounds* (VOC).
» Range = 0 to 100 ppm or 0 to 1000 ppm.
» Resolution = 0.1 ppm or 1 ppm.

Note*: The Photo Ionisation Detector (PID) type sensor is used for detection of PH3, C6H6 and VOC gases.
