The Riken Keiki OX-600 is an indoor stand-alone Industrial Oxygen (O2) Depletion and Enrichment monitor. The OX-600 is an affordable solution for use where Oxygen (O2) monitoring is required. Many facilities such as Laboratories and Hospitals, store and use quantities of Inert Gas or Oxygen. Inert Gases like Nitrogen and Argon can rapidly displace Oxygen (O2) and can kill by asphyxiation as a result. Increased levels of Oxygen (O2), even by a few percent, can present a fire risk. Industrial Oxygen (O2) Depletion Detectors are very important in these applications. OX-600 is suitable for Oxygen (O2) Depletion as well as Oxygen (O2) Enrichment.
Allows connection to remote control panel, PLC or BMS.
Easy to install.
Easy connection to external accessories such as remote sounder beacons, data loggers and dialers.
Displays real time actual Oxygen levels, desired by HSE Inspectors.
Easy readable alarm status.
Flexibility for any application.
Eliminates false alarms due to pressure changes.
Monitor can be located outside the room, with sensor inside to evaluate adequacy of a room prior to entry.
The OX-600 displays Oxygen (O2) levels on an LCD screen that changes colour at each alarm level. This is a unique feature of the Riken Keiki 600 series.
The Gas Detection Unit comes with pre-set alarms in Low and Low Low. Users can program their own alarm levels if desired.
Users can access relay outputs for 1st and 2nd alarms, in addition to a 4-20mA output. These features allow customers to connect optional external accessories such as additional sounders and beacons.
The Instrument comes ready to operate with a 24VDC power supply as well as a Battery Powered option. An optional 240VAC main adapter is available.
The OX-600 has an affordable galvanic Oxygen(O2) sensor, in addition, customers can replace the sensor in the field without the need for specialist tools.
The sensor has a pressure compensation feature to avoid false alarms.
The OX-600 has an extender cable, allowing the unit to be mounted outside of a room with the sensor inside. Personnel can evaluate adequacy of the room prior to entry as a result.
Optional accessories are available. These include a Battery backed UPS (WPSU-24 Series ) in addition to a sounder beacon(s) (Accessories) .
Typical OX-600 applications are Laboratories, Hospitals, Gas Storage rooms, Clean rooms, in addition to Cryogenics storage facilities and Warehouses.
The OX-600 is a member of the 600 series of standalone monitors, and the family includes OX-600, RI-600, EC-600, GM-600.
