| The EC91 Process Oxygen Transmitter will detect levels of oxygen as low as 1ppm, up to high percent levels and can be used on 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. It will not be harmed by oils, common acids and alkalis, making it suitable for harsh environments. It is protected to IP65. The EC91 transmits a 4-20mA signal which corresponds to the range of the analyser. Up to six ranges can be specified. A safe area digital indicator and alarm is available as an option. Custom designed sample systems are available on request. Sample gas may be piped directly to the instrument or remote cell assembly (also certified intrinsically safe). Sample pumps and aspirators are also available. All the electronic circuits are intrinsically safe and have been certified to ATEX. The EC91 is approved for EEx ia IIC T4.
