Ideal for creating a wireless network that monitors gas concentration, the Crowcon Detective+ allows the user to create a fully comprehensive wireless network that transmits data from one Detective+ to the other units up to 100m away.

Please note that a Detective Net wireless module (sold separately) is required for direct wireless transmission. Standard wired connections are also possible using this detector.

This version of the Detective+ is capable of detecting methane (CH4), Oxygen (O2) and hydrogen sulphide (H2S). When a threshold is exceeded the Detective+ that picks up on this will emit an audible tone and shine extremely bright clustered LED indicators. If it is configured across a network, the detector that picks up on the gas content will transmit its data directly to all other units, allowing the user to trace the problem.

Crowcon's Detective+ is suitable for use in a wide variety of applications, including oil and offshore applications, stationed around gas equipment, in confined spaces, industrial spaces and much more. Thanks to its wireless nature, making a network with the detectors is non-obtrusive, easy to perform and gives comprehensive safety against gas.

Note: The Detective+ can be supplied non-pumped or pumped sensors. It can also come with a standard or extended battery.
