Oxygen Deficiency Monitor for Personnel Safety & Confined Space Monitoring
Series 1300 Oxygen Deficiency Monitor for Personnel Safety & Confined Space Monitoring
Nitrogen, argon, helium, carbon dioxide, and other inert gases can silently displace oxygen, creating hazardous atmospheres that put workers at risk. The ALPHA OMEGA INSTRUMENTS™ Series 1300™ Oxygen Deficiency Monitor provides continuous ambient oxygen monitoring with audible and visual alarms to help protect personnel before oxygen levels become dangerous.
Designed for laboratories, cryogenic facilities, industrial plants, semiconductor fabs, medical gas storage, and confined spaces, the Series 1300 delivers reliable oxygen deficiency monitoring using an extended-life electrochemical sensor with proprietary Enhanced Electrolyte System (EES) technology for long sensor life, stable performance, and low maintenance.

Why Monitor Oxygen Deficiency?
Many industrial gases are colorless, odorless, and non-toxic, yet they can displace oxygen without warning.
Continuous oxygen deficiency monitoring helps:
- Protect personnel
- Detect oxygen displacement immediately
- Meet facility safety procedures
- Reduce confined-space hazards
- Improve emergency response
- Support OSHA compliance programs
- Increase worker confidence
The page already references OSHA’s definition of an oxygen-deficient atmosphere as below 19.5% oxygen and notes that oxygen levels below 16% are dangerous to human life.
Why the Enhanced Electrolyte System (EES)?
The Series 1300 features proprietary Enhanced Electrolyte System (EES) technology designed to extend sensor life and improve long-term measurement stability.
Benefits include:
- Longer sensor life
- Reduced maintenance
- Improved stability
- Better resistance to humidity
- Better resistance to harsh environments
- Lower operating costs
- Faster sensor response

Frequently Asked Questions
What is an oxygen deficiency monitor?
An oxygen deficiency monitor continuously measures ambient oxygen concentration and activates alarms if oxygen levels fall below safe thresholds, helping protect personnel in areas where inert gases may displace breathable air.
Why is oxygen deficiency dangerous?
Oxygen-deficient atmospheres can develop without warning when gases such as nitrogen, argon, helium, or carbon dioxide displace oxygen. Because these gases are often colorless and odorless, continuous monitoring is essential for worker safety.
Where should oxygen deficiency monitors be installed?
Typical installation locations include laboratories, confined spaces, cryogenic storage rooms, semiconductor facilities, industrial gas plants, MRI suites, chemical plants, and anywhere inert gases are stored or used.
What gases create oxygen-deficient atmospheres?
Common gases include:
- Nitrogen
- Argon
- Helium
- Carbon dioxide
- Other inert gases used for blanketing, purging, or cryogenic storage
How many sensors can the Series 1300 support?
The Series 1300 can be configured with one local sensor and up to two remote sensors, allowing one controller to monitor multiple locations.
