Crowcon - a leading manufacturer of specialist gas detection equipment – announces the launch, in August 2015, of a new portable multigas detector which integrates innovative features, providing advanced protection for employees working in harsh environments and minimising the cost of ownership through faster servicing. The T4 detector will enable companies to ensure compliance to safety standards by protecting employees against unsafe levels of the most commonly monitored gas combination carbon monoxide (CO), oxygen (O2), hydrogen sulphide (H2S), and a range of flammable gases.
