The JUM 3-800 is a compact 19″ rack mount heated total hydrocarbon (THC) analyzer. The JUM 3-800 uses a hydrogen flame ionization detector (FID) in a heated oven to prevent the loss of high molecular weight hydrocarbons. The burner air supply is built in.  This is the most compact version of the JUM heated FID available.  It includes an optional 50 liter metal hydride fuel storage system which allows at least 45 hours of uninterrupted operation.
