Hydrocarbon Analyzer
model HA-771
Continuous hydrocarbon analyzer based on hydrogen
flame ionizing detection method (FID) complying withJIS B 7956.

Hydrocarbon Analyzer
HA-771High sensitivity continuous measurement of CH4 ,NMHC and THC.

Large capacity memory to save measured data forover a year.

HA-771 simultaneously-measures both methane and nonmethane hydrocarbons byseparating the air sample using the gas chromatograph. The FID sensor detects theion generated by burning in the hydrogen flame as very small electric current.

USB memory for general-purpose is available todata extraction.

Ethernet interface is available as standard
equipment for digital telemetering

Simple operation on a large color LCD touch paneloffers a lot of information.
