The Riken Keiki RI-600 is an indoor stand-alone Carbon Dioxide (CO2) monitor. When Carbon Dioxide(CO2) leaks into a room it will displace Oxygen (O2). This results in Oxygen deficiency. In addition Carbon Diixode (CO2) is highly toxic in its own right.
The use of Carbon Dioxide (CO2) Monitors is extremely important as even small amounts of Carbon Dioxide (CO2) can cause death long before Oxygen (O2) Deficiency does.
The Carbon Dioxide (CO2) LTEL is 5,000 ppm or 0.5% volume. In otherwise fresh air, the oxygen channel will read 20.8 % volume, instead of 20.9% volume – nowhere near an asphyxiation hazard alarm. In fact, the STEL for Carbon Dioxide (CO2) is 1.5% volume, so even if the Carbon Dioxide (CO2) level reaches that point, it will only cause a reading of 20.6 % volume oxygen. So even when there is an immediate danger from the Carbon Dioxide (CO2), the oxygen reading is still far away from an alarm condition.
Allow connection to Remote control panel, PLC or BMS
Very easy to install
Easy connection to external accessories such as remote sounder beacons , data loggers and diallers
Displays real time actual Oxygen levels as desired by HSE inspectors
Easy to see alarm status
Flexibility for any application.
eliminates false alarms due to pressure changes
Allows monitor to be outside the room with sensor inside to ascertain state of room before entry
Allows modular system build to suit all requirements
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.
The Instrument comes ready to operate with a 24 VDC Power supply. An optional 240VAC Main adapter is also available.
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.
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 high performance cost effective solution when CO2 monitoring is required.
Accessories available include Additional Sounder Beacons and Battery backed power supplies.
