The OVF-3000 is a Portable light weight, over the shoulder portable heated FID analyzer to continuously measure the total concentration of hydrocarbons within a gaseous sample. This can be ambient air, exhaust gases from a combustion process like stack gas emissions, from any type of an industrial vent, from an internal combustion engine, or from any other emission containing hydrocarbons. The standard OVF-3000 is equipped with a modern low pressure metal hydrid fuel storage system which is good for continuous operation for 50 hours. This fuel Storage can be safely refilled by the user from a low pressure H2 source.

By measurement results the OVF-3000 fully complies with EN 12619.2013, QAL 1 (EN 14 181 and EN ISO 14956), and with USA EPA Method 25A and Method 503. It is ideally suited to be used for temporary monitoring all stack emissions.
