OMD-675 Oxygen Analyzer

Brand: Southland Sensing Ltd

The OMD-675 is designed to measure trace oxygen in the sub 1 ppm region. 

The unit combines an advanced set of electronic features with our industry leading precision electrochemical oxygen sensor technology. 

The result is a highly reliable and cost effective design with an easy-to-use user interface. 

The analyzer comes with a 0 - 1 PPM full scale low range with a resolution of 0.001 ppm. 

The analyzer can also be configured for 0 - 1 ppm, 0 - 10ppm, 0 - 100ppm, 0 - 1000ppm and 0 - 25% in autorange or manual-range mode. 

The analyzer offers the user 2 different digital communication options, both of which are bi-directional. 

These come in the form of MODBUS RS485 ASCII or RS232. 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.
