- Model 3-200 - Portable High Temperature Total Hydrocarbon Analyzer



Our transportable model 3-200 fully heated FID is successfully used throughout international markets for over 30 years. Also among other portable gas FIDs, the 3-200 It is the first ever built transportable fully heated FID using our proprietary back purge sample filter. It is widely distributed throughout the industry and the stack testing community and is much liked for its ruggedness, high accuracy, sensitivity and stability. Our optional 50 liter low pressure metal hydride fuel storage can easily be mounted on the left side panel and allows a 45 hour minimum of uninterrupted operation. This fuel storage can be self-refilled at a low pressure of only 25 bar. No special adapter needed. A standard 2-stage pressure regulator with a 30 bar outlet is sufficient.

The 3-200 is officially certified to be 100% identical to the VE7 and 3-300A analyzers. It is TUV approved and certified for 2. BImSchV. 13. BImSchV and 17. BImSchV and fully complies with EN 12619, EN 13526 (EU) and with EPA Method 25A and Method 503 (USA).

The J.U.M. Engineering HFID Model 3-200 is a portable very compact heated total hydrocarbon analyzer for high accuracy, sensitivity and stability.

The very reliable Model 3-200 heated FID uses our time proven hydrogen flame ionization detector (FID) in a 190°C heated oven to prevent the loss of high molecular weight hydrocarbons and to provide best performance in the analysis of low trace to high concentration levels of contaminants in emissions, ambient air, high purity gases, air and other gases.

All sample wetted components are integrated into the heated chamber. The permanent heated sample filter is cleaned by back purging with compressed air or nitrogen. This allows uninterrupted measurements during cleaning the sample filter. While back purging the sample filter, the sample line is also cleaned. The use of a stack probe filter is not necessary.

The combustion air supply for the detector is built in. No expensive zero gas generator or external cylinder for synthetic air is needed.

Our optional 50 liter metal hydrid fuel storage (See inserted picture) allows a 45 hour minimum of uninterrupted operation. This fuel storage can be very safely self-filled at a low pressure of 25 bar. No special adapter needed.

Also available with our highly effective methane only option.


The Flame Ionization Detection (FID) method is used to determine the presence of total hydrocarbon concentrations in a gaseous sample. Burning hydrocarbon-free hydrogen in hydrocarbon-free air produces a negligible number of ions.

Once a sample containing hydrocarbons is introduced into this flame a very complex ionization process is started. This process creates a large number ions. A high polarizing voltage is applied between the two electrodes around the burner nozzle and produces an electrostatic field. Now negative ions migrate to the collector electrode and positive ions migrate to the high voltage electrode. The so generated ionization current between the two electrodes is directly proportional to the hydrocarbon concentration in the sample that is burned by the flame. This signal is measured and amplified by our electrometer-unit.

A sample pressure regulator provides a controlled back pressure at the sample capillary which gives admittance of a constant sample flow rate to the burner. This technique without the conventional back pressure regulator is used by J.U.M. Engineering for over 30 years to provide the highest possible sample flow rate stability and lowest maintenance. Our compactly designed flow control module for controlling the fuel and air flow rates via needle valves use high precision pressure regulators. The needle valves are factory adjusted and sealed to ensure the optimization of the burner.
