This Crowcon T4 Multi-Gas Detector is capable of detecting Oxygen (O2), Hydrogen Sulphide (H2S), Carbon Monoxide (CO) and Methane (CH4-LEL) simultaneously. For more configurations visit here. These configurations have been approved by the Marine Equipment Directive and are safe for use in marine environments.
The rugged housing of the Crowcon T4 is made of an anti-shock rubber and its ATEX-approval means it can be used in hazardous environments. With an 18-hour battery, it can be safely used for a full working longer than a working shift.
Other advantages of using the Crowcon Tetra 4 multi-gas detector is it’s clear, backlit display, compliance indicator and single button operation. The compliance indicator flashes green if the unit is working safely and red if attention is required. Also with a triple alarm system (audible, visual and vibrating) and its innovative TWA resume function – toxic gas exposure is calculated over an entire shift (even if the unit is switched off or is travelling to a different site). The Crowcon T4 is perfect for confined space entry.
