Product Introduction

The oxygen deficiency monitor continuously measures ambient oxygen with a replaceable electrochemical or optical sensor and presents the value on a local display. Configurable low-level alarms operate relays, beacon and sounder outputs before conditions become severe. Remote heads can be positioned at the breathing zone or according to the release scenario while the display remains visible outside the room.

Key Features

Continuous oxygen indication gives personnel an immediate room-status check.

Two alarm stages support ventilation and evacuation actions.

Sensor and system faults are separated from gas alarms.

Remote outputs integrate with ventilation and access-control logic.

Customer Product Concerns

Inert gases are odorless and can displace oxygen without visible warning, especially in enclosed utility spaces.

Personnel cannot sense oxygen depletion directly.A fixed sensor continuously measures and displays oxygen concentration.

A single high alarm provides little time for corrective action.Staged low alarms can start ventilation before evacuation level.

Sensor end-of-life can mimic a safe reading.Fault monitoring and scheduled replacement maintain measurement integrity.

The safest display location may differ from the sensing point.Remote-sensor configurations separate the room sensor from the entrance display.

Typical Applications

Nitrogen utility roomsCryogenic storage areasInert-gas process suitesLaboratory gas storage
