About CO / Carbon Monoxide Detectors

Carbon monoxide (commonly abbreviated as CO) is a colourless, invisible, and harmful gas. Due to its toxic nature and invisibility, being forewarned against the presence of this gas is essential, particularly in environments where the gas is regularly used.

A CO detector can vary greatly in design and suitability. Some items are small-size, pen-shaped instruments that simply alert the user to CO presence, while others are advanced meters with specialist probes designed for checking the level of carbon monoxide within an appliance such as a flue.

The abilities of the detector will also vary depending on the model. Some basic instruments are designed purely as an indicator with audible/visual signals, while others include an LCD screen that shows the ppm value of CO in the atmosphere. Many instruments also include both of these abilities.

At PASS, we stock popular and industry-leading models from renowned gas equipment manufacturers such as Fluke, Kane, and Testo for highly competitive prices.
