Southland Sensing - Model OMD-675 -19 Inch Rack Mount Online Trace Oxygen Analyzer, CE

• Enclosure Type: 19″ Rack Mount
• Available Ranges: 0 – 1/10/100/1000 PPM & 0 – 25%
• Range Mode: Auto-Range or Manual Range
• Resolution: 0.001 PPM
• Input Power: 100 – 240 VAC
• Analog Output: 4 – 20mA, 0 – 10V DC, 0 – 1V DC
• Communication: Bi-Directional MODBUS RS485 RTU

The built in smart MENU interface allow the user to fully configure the analyzer through the onboard MENU system.  No need for a complicated laptop or other control device to setup the analyzer in the field.

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.

Designed to measure trace oxygen in the sub 1 ppm region (Parts-Per-Billion, Parts-Per-Million & Percent Oxygen Values). The unit combines an advanced set of electronic features including a smart MENU interface along with our industry leading precision electrochemical oxygen sensor technology. The result is a highly reliable and cost effective 19″ rack mount oxygen analyzer with an easy-to-use user interface.

Specific applications typically include continuous real time monitoring of air separation, pharmaceutical & semiconductor processes.

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.

The oxygen sensor used in the OMD-675 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.
