Instrument designed for metrological veri­cation of volumetric sampler meters. Equipped with sensors for detecting atmospheric pressure, absolute pressure, and temperature at the meter, it can be certi­ed and used as a reference instrument for instrumentation veri­cation. The feature that makes GEO GM Meter unique is the use of a meter that incorporates the features of traditional G 1.6 / G 2.5 / G4 meters.
It allows the temperature and pressure of GEO and MACH series samplers to be easily and immediately aligned to the same value as the GEO GM METER.

All alignment operations can be performed WITHOUT OPENING THE INSTRUMENT which saves time for those who periodically perform these activities, such as ACCREDITED laboratories.

EOLO WIND TUNNEL is ideal for ACCREDITED laboratories that need a system for calibrating the instrumentation used for emission flow rate measurement.

Equipped with a double nozzle, it allows the calibration of the constant of the Pitot TUBES and/or veri­cation of the measurement lines (gauge and Pitot tube) at different speed values: minimum DP of 5 Pa – Variable speed up to 30 m/s.

The design follows the construction speci­cations in EN 15259 to ensure laminar flow.
