Oxygen Deficiency Monitoring in Laboratories & Research Facilities

Personnel Safety Monitoring Wherever Inert Gases Are Used in the Lab — OMD-351

Research laboratories routinely use nitrogen, argon, helium, CO2, and other inert or asphyxiant gases for everything from sample preparation to instrument purging, often from cylinders or small bulk sources inside the lab itself. In enclosed lab spaces, a leak or an open valve can lower oxygen levels well before anyone notices the change.

The OMD-351 fixed area oxygen monitor gives laboratories and research facilities continuous personnel safety coverage, alarming if oxygen levels drop due to a leak or equipment malfunction near gas cylinders, dewars, or supply lines.

Why Laboratory Oxygen Safety Matters

Labs often combine multiple inert gas sources, cylinders, liquid nitrogen dewars, and gas lines feeding instruments, in a single enclosed room, which raises the cumulative risk of oxygen displacement compared to any one source alone. Continuous area monitoring with audible and visual alarms gives lab personnel immediate warning if oxygen begins to drop, supporting safe evacuation before exposure becomes dangerous.

Where It's Used

General chemistry and research labs monitoring near cylinder gas supplies
Sample prep and instrument rooms safety coverage near purge gas connections
Cryogenic sample storage areas monitoring near liquid nitrogen dewars
Shared core facilities and instrument rooms supporting safe entry for all lab personnel

OMD-351 Fixed Area Oxygen Deficiency Monitor

The OMD-351 is a fixed, wall or panel-mounted oxygen deficiency monitor designed to provide continuous area safety coverage in laboratories and research facilities.

With integral audible and visual alarms, the OMD-351 alerts lab personnel immediately if oxygen levels drop due to a leak or malfunction, supporting safe evacuation before conditions become hazardous.

Especificações principais

Range: 0 – 25% O2, covering normal atmosphere down to hazardous deficiency levels
Alarms: dual-stage audible and visual alarms configurable to lab safety thresholds
Response time: fast detection suited to area safety monitoring requirements
Output: 4-20 mA for integration with facility safety and BMS systems
Enclosure: fixed wall or panel-mount design suited to laboratory installation

Perguntas Frequentes

What inert gas sources typically require area oxygen monitoring in a lab?

Trace oxygen measurement provides a direct indication of oxygen contamination or crossover into the hydrogen stream. Trending the oxygen concentration can help operators identify changes in electrolyser or purification system performance.

Where in a laboratory should the OMD-351 be installed for best coverage?

A common measurement point is the hydrogen product stream downstream of the electrolyser stack. Additional measurement points may be used before or after drying and purification equipment depending on the process design and monitoring objectives.

Can the OMD-351 integrate with an existing lab safety or BMS system?

Alarm and control limits should be determined based on the electrolyser manufacturer’s specifications, process conditions, applicable standards, and the facility’s safety requirements rather than using a universal oxygen alarm value.
