Equipped with an IR sensor, the Crowcon Detective+ is the tool you need for monitoring gas within an area. The IR sensor allows the instrument to detect gas across a wider measurement range and is also designed to last longer than standard flammable gas sensors.

Suitable for detecting both methane and oxygen, the Detective+ sits wherever you need it and will emit a loud audible tone and shine bright LED indicators whenever its thresholds are exceeded.  You can either use the unit as a single instrument, or alternatively you can combine it together with several other Detective+ instruments and Detective Net Wireless Modules (sold separately) to create a comprehensive gas monitoring network!

This network allows wireless transmission of data from one Detective+ to the next, even if its 100m away. Up to 25 individual testers can be configured to work within the network, allowing comprehensive detection in confined spaces and similar applications. The following video outlines the features of this mode.

This version of the Detective+ is available either non-pumped or pumped. Use the dropdown box above to select which you'd prefer.
