Crowcon Detective+ 3 Gas Multigas Area Monitor - CH4, O2 & CO Details

Note: Detective Net Wireless Modules (sold separately) are required to create a wireless network using Detective+ units.

Suitable for use in everywhere from confined spaces to standard industrial environments, the Crowcon Detective+ constantly monitors the environment in order to detect three different gasses (methane, oxygen and carbon monoxide).

By using multiple Detective+ units it's possible to create a fully comprehensive gas monitoring network that transmits data wirelessly from unit to unit. For example, a Detective+ within a confined space would pick up on a gas leak, transmit its data to a nearby unit (up to 100m away) and both units would simultaneously sound alarms and shine LED indicators. It's then possible to use a safe unit (not inside the space) to trace the original problem and take corrective action. Up to 25 individual Detective+ units can be connected up in this way, ensuring full coverage over the entire area.

We can supply the Crowcon Detective+ with either an extended or standard battery and pumped/non-pumped sensor. See the dropdown box options above for more information.
