MEXA-1170HFID

MEXA-1170HFID - Evaporative-Emission Samples

Heated Type THC Analyzer

With 14 selectable ranges - from 0-10 ppmC to 0-200,000 ppmC - MEXA-1170HFID can measure direct, CVS/tunnel-diluted, and evaporative-emission samples.

A ten-key control pad and a color LCD make it easy to monitor the test data. Data transfer to a remote computer is possible via RS-232 or an optional analog output.
