1. This machine is designed especially for export in according to foreign customer's special request, and exported for many times in large batches. The product conform the specified requirement on rack of Environmental Prolection Industry Standard (HJ/T396-2007, HJ/T291-2006. and HJ/T292 2006)-Applicable for light-duty gasoline fueled and diesel vehicle to detect exhaust emission.

2. Bending steel plates and welded into rack: flywheel is combined with primary roller within coaxial: ultra-low internal loss power design; accurate basic inertia;  reasonable structure; exquisite technique; cool appearance; an improved force calibration tool is adopted to make the calibration process easicr.

3. Air-cooled vorlex machine adopted new fan blade with prefect radialing and low wind resistance. The coaxial roller is connected by a new special rubber coupling to reduce noise. 7.5kw drive motor with frequency converter can use fornfinitely tuning speed, and accurately to measure the machine's internal loss power.
