Carbon Dioxide ( CO2)  Monitor:

The Riken Keiki RI-600 is an indoor stand-alone Carbon Dioxide monitor.

When Carbon Dioxide leaks into a room it will displace Oxygen. This results in Oxygen deficiency.  In addition CO2 is highly toxic in its own right.

The use of Carbon Dioxide Monitors is extremely important as even small amounts of CO2 can cause death long before Oxygen Deficiency does.

Visual and Audible CO2 Alarms:

The RI-600 displays CO2 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 High and High High. 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 such as additional sounders and beacons.

Optional extras that include a Battery backed UPS ( BATPSU-600-X-24VDC) and additional sounder beacon(s) (SB-600-24VDC ) are available.

The Instrument comes ready to operate with a 24 VDC Power supply.  An optional 240VAC Main adapter is also available.

Sensor Technologies :

The RI-600’s Sensor is highly accurate and extremely long lived. It uses Non-Dispersive Infrared Ray Absorption ( NDIR) technology to achieve this.

The RI-600 comes with a measurement range of 0-5% Volume OR 0-10000ppm. Users can program levels for 0-2% or 0-2000ppm or 0-5000ppm if required.

Remote Carbon Dioxide ( CO2 ) Sensor:

An extender cable allows the unit to be mounted outside the room with the sensor inside. This allows users to ascertain the state of the room prior to entry.

Laboratories, Breweries, Greenhouses, Underground car parks in addition to Office buildings and conference rooms are applications that can benefit from CO2 Monitoring

The RI-600 is a member of the 600 series of standalone monitors. The 600 Series family also includes OX-600, EC-600 and GM-600 

The RI-600 is a high performance cost effective solution when CO2 monitoring is required.
