OMD-690 Explosion Proof Oxygen Analyzer

Description

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.

L'interface MENU intelligente intégrée permet à l'utilisateur de configurer entièrement l'analyseur par le biais du système MENU embarqué. Pas besoin d'un ordinateur portable compliqué ou d'un autre dispositif de contrôle pour configurer l'analyseur sur le terrain.

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.
