MEASURE. ANALYZE. CONTROL. Product Specification Sheet Online Trace Oxygen Analyzer w/ Integral Sample System 0 - 1 PPM Low Range; 0 - 25% High Range Resolution of 0.001 Parts-Per-Million Oxygen Integral Sample System w/ Bypass Valve Bi-Directional Communication Link Extensive Electronic Features & Outputs Panel Mount Configuration Electrochemical Sensor Technology The 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. The standard cell (TO2-133T) is unaffected by other background gases such as H2, He, or Hydrocarbons. The optional acidic cell (TO2-233T) works well when acid gases such as CO2 or Natural Gas are present. The sensors are self-contained and minimal maintenance is required -no need to clean electrodes or add electrolyte.
