Description:
The J.U.M. Engineering HFID Model 3-400 is
a compact wall mount heated total hydrocarbon analyzer for high
accuracy, sensitivity and stability. It is housed inside a rugged
and sealed NEMA 4 enclosure.
The Model 3-400 uses our proven "VentDownTM" hydrogen flame ionization
detector (FID) in a heated oven to prevent the loss of high molecular
weight hydrocarbons and to provide reliable performance in the
analysis of trace level of contaminants in high purity gases,
air and other gases. The "VentDownTM" design of the detector allows easy maintenance
and helps preventing blockage of the detector exhaust.
All sample wetted components are integrated
into the heated oven. The oven temperature is controlled by a
microprocessor controlled temperature controller.
The permanent heated sample filter is cleaned
by backpurging and has a replaceable stainless steel 2µm
mesh filter disc. The burner air supply is built in. No extra
bottles for combustion air are needed.
Major Applications:
- Stack gas hydrocarbon emissions monitoring
- Catalytic converter testing
- EPA method 25A compliance monitoring of source
hydrocarbons
- Raw exhaust vehicle emissions
- Solvent recovery monitor of carbon bed break
through
- Monitoring of hydrocarbon contaminants in
air and other gases
- Carbon adsorption regeneration control
- Measuring engine combustion efficiency
- LEL monitor of solvent-laden air
- Cryogenics/liquefaction
- Clean room applications
