Paramagnetic Oxygen Analyzer SR-2030ExP (Flameproof Type) 

Paramagnetic oxygen analyzer adopts a flameproof enclosure. We adhere to the principle that an explosion proof oxygen analyzer should have excellent shell strength and maximum surface temperature. The circuit is isolated from the surrounding environment, thus can prevent ignition of flammable and explosive gases around it. This paramagnetic oxygen analyzer is used to carry out continuous oxygen concentration measurement.

This gas analyzer is suitable for the detection of explosive gas and its mixture containing the IIC T6 group and below and the mixture of steam and air for hazardous areas of zone 1 or 2.

Application areas

Industrial fields of chemical fertilizer, chemical industry, metallurgy, air separation, and cement production, and continuous detection on gas concentration in fields of environmental protection and pollution source.
