Intrinsically Safe o2 analyzers EC91






Intrinsically safe ATEX-approved EC91, unsurpassed o2 analyzers for all hazardous areas.

Intrinsically safe ATEX-approved EC91 is an unsurpassed oxygen analyzer for all hazardous areas.

The EC91 intrinsically safe oxygen analyzer is an online transmitter for ppm and percent oxygen measurements of gas streams in hazardous area installations. It can detect oxygen levels from as low as 1 ppm up to higher percent levels and can be used in most industrial gases and atmospheres. There is no need for routine maintenance of the fuel cell and the instrument can be easily calibrated, using ambient air or standard calibration samples.

The enclosure is manufactured from moulded glass fibre reinforced polyester, a material with high impact resistance making it suitable for harsh environments. It is protected to IP66 / NEMA 4X.

All the electronic circuits are intrinsically safe and have been certified to ATEX. The EC91o2 analyzers are approved for use in Ex ia IIC T4 Ga – Zone 0 areas.
