APHA-370

Hydrocarbon Monitor / THC Analyser

Our APHA-370 measuring device is a continuously operating analyzer for determining Total hydrocarbons (THC), CH₄ and non-CH₄ in the ambient air. Further applications exist in various areas of process and trace analysis. The Horiba measuring device APHA-370 is a flame ionization detector that uses the "cross flow modulation principle". Measuring gas and reference gas are fed alternately to the measuring cuvette. The measurement gas serves as the reference gas. in which the THC concentration was eliminated. This guarantees low-maintenance operation and extremely stable measurements. The measuring device is almost interference-free and has an internal measuring gas pump. The burner air is generated from the ambient air and fed to the detector.

Segment: Process And Environmental

Division: Ambient

Manufacturing Company: HORIBA, Ltd.

Base product: AP-370 Series

• Selective combustion flame ionization detector measures total hydrocarbon (THC), NMHC and CH₄ simultaneously.
• Single detector eliminates zero drift; Low range: 0-5 ppmC F.S.
• Integrates relative sensitivity correction for CH₄ and NMHC.
• Integrates a reference and combustion air generator, NMHC cutter and sample pump.
• Requires H₂ as fuel gas for the FID.
