Riken Keiki Model OX-04 Represents the latest iteration of Robust yet cost effective Riken Single gas personal Monitors
Facilities such as Oil Refineries, Petrochemical Storage Facilities, Water and Wastewater Treatment plants, Pharmaceutical labs, Utilities, Fire fighting and Chemical Plants are hazardous areas. Workers and Visitors need personal gas protection at all times without the addition of extra bulky equipment. Personal Single Gas Monitors are ideal for this.
Disposable gas detectors are low cost but users can suffer high failure rates, this can result in safety concerns. Users often find the cost of ownership often outweighs the small initial cost saving over a reliable renewable gas detector. Customers constantly have to replace failed units resulting in personnel down time and the lost productivity.
The Riken Keiki 04 series are personal single gas monitors designed for protection from exposure to, Oxygen Deficiency, Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulphur Dioxide ( SO2 ), Hydrogen Cyanide (HCN), Nitrogen Dioxide (NO2), Phosphine (PH3), Ammonia (NH3), Chlorine (CL2) (due 2022) and Carbon Dioxide (CO2) (due 2022). Users of the O4 Series find the units are robust, reliable, long-lasting, and cost effective. In addition they have a digital display, can be calibrated, and are dust and water-resistant (IP-68). The 04-Series has a replaceable rubber boot in addition users can data log from 5 to 300 hours with adjustable intervals.
The 04 series personal single gas monitors have 3 preset alarms. The user can adjust the alarms to their own levels if desired. Each version is equipped with visual, audible, and vibration alarms as standard. The replacement sensors are inexpensive. Users can replace the sensors in the field. Customers can expect Sensors to have a life expectancy of 3-5 years in addition they are interchangeable with other Riken Keiki monitors.
