OMD-690 Explosion Proof Oxygen Analyzer

说明

The OMD-690 Explosion Proof Oxygen Analyzer is designed to measure trace oxygen in the parts-per-billion range / sub 1 ppm region but can also be used to measure oxygen up to 1000 parts-per-million. The unit combines an advanced set of electronic features including a smart MENU interface including our innovative touch glass technology with our industry leading leading precision electrochemical oxygen sensor technology. The result is a highly reliable and cost effective design with easy-to-use user interface for petrochemical and chemical applications.

Alarm functionality comes in the way of 2 fully adjustable form C non-latching relay contacts. These can be configured as NO or NC and can be set as HIGH or LOW with optional delay mode. A power failure alarm is also standard and comes as a form C non-latching relay contact.

The analyzer is designed as an extractive type unit to draw the sample through its integrated sample system which includes a bypass / isolation valve, flow needle valve and a visual rotameter / flowmeter.

The standard cell (TO2-133) is unaffected by other background gases such as hydrogen, helium, or hydrocarbons. The optional acidic cell (TO2-233) works well when acid gases such as CO2 or Natural Gas are present.  All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict ISO9001:2015 / ISO13485:2016 quality system.

The sensors are self-contained and minimal maintenance is required – no need to clean electrodes or add electrolyte.
