OMD-677 Oxygen Analyzer
Brand: Southland Sensing LtdThe OMD-677 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 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.
This comes 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 nonlatching relay contact.
The oxygen sensor used in the OMD-677 is based on the galvanic electrochemical fuel cell principal.
All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program.
