Description

Crowcon Detective+

The Detective+ portable area monitor builds on the reputation, dependability, and adaptability of its predecessors, the immensely popular Triple Plus+ and Detective models. The Crowcon Detective+ has a strong, fixed or folding leg protection frame that is incredibly durable. Inter-Detective+ units can communicate loud and clear alarms, and an optional built-in pump enables faster gas reaction and improved sensor protection.

Detective+ can now be equipped with infra-red sensor technology. This provides either CO2 detection or allows higher flammable gas level monitoring. It provides immunity to the poisoning effects that standard flammable gas sensors can suffer from.

The battery capacity now comes in two options: 36 hours or 60 hours, with standard configuration, giving remote sites more time between charges. When these characteristics are combined with the variety of hazardous gas sensors that are offered, Detective+ becomes one of the most adaptable area monitors on the market.

There can be no mistaking 55,000 Detective and TriplePlus+ gas detection users.
