Comark Pressure / Manometers – Intrinsically Safe

Comark KM-9500 Ex/I.S

Our Intrinsically Safe Pressure Meters contain impregnated protection, designed to limit electrical discharge as well as the surface temperature of the device, in order to prevent the possible ignition of a volatile gases, dust or vapours.

The Comark range of Intrinsically Safe Manometers are ATEX compliant, certified to Ex II 1G Ex ia IIC T4 Ga and Baseefa 03ATEX0079 and are therefore recommended for use in areas where explosive or flammable substances are stored or processed. These pressure meters have been approved by internationally recognised approval bodies to intrinsic safety requirements.
