T4 4 Gas Detector with Sensor Guard

Product Sku: 778964

A gas detection unit of any kind is a vital piece of equipment for crew members entering any enclosed space or tank. The SOLAS XI-1/7 regulation approved by MSC 93/94 requires all ships engaged in international voyages to have a minimum of one portable 4-gas detection unit onboard.

The T4 Gas Detection Unit offers compliance, robustness and low cost of ownership in a simple to use solution. A large single button and intuitive menu system allows the user to operate the unit even when wearing gloves.

Additionally, the T4 unit ensures durability by design and includes an integrated rubber boot as standard. An optional clip-on filter cover, which is easily removed and replaced, ensures sensors are protected in the dirtiest environments. When it comes to gas detection the vessel will always be regulation ready.
