Pro vs Expert
Turbo Test Duo Pro
In addition to the high-speed balancing feature, the machine enables you to calibrate turbochargers by the adjustment of the air mass flow of the turbine section. The measurement can be conducted in a static or dynamic mode. The dynamic mode enables you to measure the rotational speed of turbocharger. As a result it is possible to determine turbocharger’s technical condition and its more precise adjustment than in case of the static mode.
Turbo Test Duo Expert
This model of the machine enables you to restore 100% turbocharger’s performance by its calibration according to turbocharger’s pressure ratio measured under load at high speeds. The pressure ratio is turbocharger’s outlet parameter that defines its performance. It enables the precise determination of turbocharger’s technical condition and its most accurate calibration.
