Remote Oxygen Depletion Safety Alarm
The RAD-0002 Remote Oxygen Depletion Safety Alarm is designed to protect customers and workers near stored inert gases like nitrogen, argon, helium, and others.
Low oxygen alarms are critical in inert gas storage facilities, cryogenics, cryotherapy, food production facilities, or in any enclosed space where gas tanks or cylinders are stored indoors.
- Wired O2 Monitor & Remote Display
- Reliable connection with a standard Ethernet cable (25 ft. included)
- Large display clearly indicates current O2 level and temperature
- 3 relays automatically control fans to ventilate confined spaces
- 4-20 mA output to allow for remote display of values
- 88dB audible and visual alarms on both units
- IP54 Enclosure - prevents water damage during wash-down
- 100% clean look – all cables can be hidden
- UL Listed for Compliance
The Monitor has both audible and visual alarms. 3 built-in relays are triggered at 19.5%, 17%, and 15% respectively that can control an exhaust fan or send an alarm to the fire department or monitoring company. The first audible and visual alarms will activate when the oxygen concentration falls below 19.5% per OSHA requirements. The alarm levels are user-configurable to allow for specific applications.
The Oxygen Depletion Safety Alarm is easy to install and use. Simply mount both units on the wall (all cables and hardware included), plug the monitoring unit into a standard wall outlet, and the alarms are ready to protect your customers and employees.
