The RAD-0002-ZR Oxygen Deficiency Safety Monitor is designed to detect extremely low concentrations of oxygen in enclosed spaces and to warn occupants of low oxygen levels. This device can also monitor either O2 depletion or O2 enrichment, as hazardous concentrations of oxygen (O2) in confined spaces are dangerous, and may lead to health problems ranging from headaches and fatigue to asphyxiation and even fatality.
This monitor has both audible and visual alarms, which will alert individuals should hazardous concentrations be present. Detection of low levels of O2 will also activate relays that can be used for a fan or air-handling system to ventilate the confined space and improve O2 concentration in the area.
Features:
- Large digital LCD display.
- Separate SEU (Main Sensor) and RDU (Remote Display).
- 3 Relay outputs to control ventilation devices.
- 4-20mA Outputs – O2: 0~25%, Temp: -50°C.
- Audible and visual indications at 3 alarm levels.
- Ability to add strobes for additional indication.
- Automatic barometric pressure compensation.
