Description:
The J.U.M. Engineering Model 109A Non-Methane
Hydrocarbon (NMHC) analyzer is a compact 19" rack mount
analysis system using the FID (Flame Ionization Detector) principle.
Its modular design allows easy maintenance.
There is no additional sample handling equipment
required. The sample pump, the sample filter and all pressure
and flow regulating components are built in. All sample wetted
parts are operating at a temperature of 463K (374°F / 190°C)
or above. To avoid reading errors due to calibration gas pressure-fluctuations
the analyzer has an integral calibration gas overflow system
before the sample filter.
The Model 109A also features our dual detector/dual
electrometer design which provides three continuous, simultaneous
signals of:
- Total Hydrocarbons
- Methane/Only
- Total Hydrocarbons less Methane (NMHC)
The permanent heated sample filter is cleaned
by backpurging and has a replaceable stainless steel mesh filter
disc. A rear adaptor-system allows "cold-spot free"
coupling of a heated sample line inside the heated oven without
the need of special tools.
Major Applications:
- Stack gas emissions monitoring
- Ambient air monitoring to low concentration
levels
- Raw automotive and diesel exhaust analysis
- Thermal reactor and combustor emissions monitoring
