Crowcon T4 Multi 4-Gas Detector with Cradle Charger

The T4 multi gas detector from Crowcon is a portable 4-gas monitor for detecting LEL, O2, CO and H2S.  The gas monitor is ideal for personal monitoring and portable safety applications.  All options here come with a cradle charger. 

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.  The 18-hour battery also allows it to be safely used for a full working shift, or longer.  Crowcon has also drop tested the T4 to 4m on concrete. 

Other advantages of using the Crowcon T4 multi gas detector is it’s clear, backlit display, compliance indicator and its single button operation.  The compliance indicator flashes green if the unit is working safely and red if there’s any attention required.
