APHA-380 Hydrocarbon Monitor

Description

The APHA-380 is an analyzer for measuring hydrocarbon in ambient air and other background gases, for air quality control as well as for variety of industrial applications. HORIBA’s state-of-the-art flame ionization detector(FID) with selective combustion enables high sensitivity and stable real-time continuous measurement.

Ultimate Performance
Flame ionization detector with selective combustion provides excellent sensitivity, stability and robustness
Simultaneously measures THC, CH4 and NMHC
Real-time continuous measurement
Single detector eliminates zero drift
Wide measurement range with up to 5 ranges selectable, minimum 0-5 ppmC and maximum 0-100 ppmC
Enhanced Lower Detection Limit and response time

User-Friendly Interface & Functionality
