The Riken Keiki OX-600 is an indoor stand-alone Oxygen monitor.
The OX-600 is a low cost solution for use where O2 monitoring is required.
Many facilities store and use quantities of Inert Gas. Laboratories and Hospitals are typical of these facilities.
Inert Gases can rapidly displace Oxygen and can kill by asphyxiation as a result. Oxygen Monitors are very important in these applications.
The OX-600 displays 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 Unit comes with preset alarms set to 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 connected optional external accessories such as additional sounders and beacons.
The Instrument comes ready to operate with a 24 VDC Power supply as well as a Battery Powered option. An optional 240VAC Main adapter is available.
The OX-600 has a low-cost galvanic Oxygen sensor, in addition customers can replace the sensor in the field without the need for special tools.
The sensor has a pressure compensation feature to avoid false alarms.
As an option the OX-600 has an extender cable that allows the unit to be mounted outside the room with the sensor inside. Staff have the ability to ascertain the state of the room prior to entry as a result.
Optional accessories are available. These include a Battery backed UPS (WPSU24 Series ) in addition to a sounder beacon(s) (SB-100 ) .
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 in addition this family includes RI-600, EC-600 and GM-600
