The Century OVA

The century Organic Vapor Analyzer is the best FID (Flame Ionization Detection) unit in use today for Natural Gas Leak surveys. When looking at the unit it doesn't look flashy or hightech, however, it gives you the most accurate reading than any other instument in use today. When it comes to public safety, you want the best equipment for the job. The OVA goes back to basics. It gives a straight reading without all the fanfare. That's why for years, companies like PG&E, SoCal Gas, San Diego Gas and Electric still use the OVA today.
The portable Century OVA is reliable and accurate for continuous direct read-out of total organic vapor concentrations. The OVA 128, has three concentration ranges that span from 0 to 1000 ppm, in hazardous waste applications that include emergency spill response, site evaluations, remedial investigation and soil gas monitoring.
The application of the OVA 88 and OVA 108 is mainly for leak detection in, pipelines, process streams, landfill monitoring and EPA Method 21 testing. Concentration range is from 0 to 10,000 ppm. Both models carry FM and BASEEFA approvals for intrinsically safe use in Class I, Division 1, Groups A, B, C and D. The
dilutor kit extends the instrument’s dynamic range by a factor of about ten.
