The HWT-Pro consists of load and height verification devices, sample tray centering spacers for different model wheel trackers, temperature indicator, USB cable, HWT-Spec Software and a carrying case. The load device is made of precision machined stainless steel and quality electrical components. All measurement devices used in the HWT-Pro are NIST traceable and the unit is provided with certificate of calibration.

Verifies all AASHTO T-324 Measurement requirements
Meets recommendations of NCHRP Project 20-07 Task 361
Allows for easy and safe verification of the unit, without having to place hands and fingers close to the wheel and heavy loads
Measures wheel load, Wheel center point, waveform, displacement, and water temperature
Measures both static and dynamic wheel load
Checks accuracy of the wheel motion versus sinusoid and reports RMSE
Check calibration quality before a project or after long periods of nonuse
Quickly diagnose and trouble shoot issues with your equipment
HWT-Spec PC Software easily captures and reports verification results
HWP-Pro includes NIST traceability certificates
