Fixed Gas Detection

OX-600

Cost Effective Standalone Oxygen (O2) Deficiency / Enrichment Monitor

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 such as Laboratories and Hospitals store and use quantities of Inert Gas or Oxygen. Inert Gases like Nitrogen and Argon can rapidly displace Oxygen and can kill by asphyxiation as a result. Increased levels of Oxygen, even by a few percent, can present a fire risk. Oxygen Monitors are very important in these applications. OX-600 is suitable for Oxygen Depletion as well as Oxygen Enrichment 

Gas Detection for Hospital Applications

Product Features

Visual and Audible Oxygen Alarms:

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.

Sensor Technologies :

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.

Remote Oxygen ( O2 ) Sensor:

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 (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 in addition this family includes OX-600, RI-600, EC-600, GM-600
