EMISSION ANALYSER – VEA 401/ 501

Quick Overview

The VEA-501/401 Gas Analyzer is for measuring CO, HC and CO2 in automotive emissions by the principle of non-dividing infrared absorption, measuring NO (Not for VEA-401)and O2 by the principle of electrochemical cell, calculating excessive air coefficient  based on the composition of CO, CO2, HC and O2 measured. . It is an intellectual instrument with LCD display and English interface. Inductive RPM (engine-speed) measuring pliers, oil temperature sensor and printer are optional for measuring RPM and oil temperature, and printing measurement results.

This instrument complies with the requirements of International Measurement Rules OIML R99/1998 (E) made by the Organization of International Measurement Law (OIML) and the National Metrological Verification Regulations # JJG 688 for class-1 instruments. It is applicable for environmental departments, vehicle inspection stations, automotive manufacturing factories and garages.
