The SmarTracker has a retractable wheel system that makes it easy to load and unload samples without lifting heavy wheel assemblies. The hamburg machine can perform both wet and dry tests simultaneously. The innovative water circulation system and two tank design allows for one sample to be submerged in water while the other sample stays dry. Tank and air heaters keep water and air temperatures constant during testing. The electrical components are located away from water and moisture to protect against damage. The unit features an independent motor wheel drive system for better control and individual operation of each wheel. Operated by an on-board Windows® based touchscreen computer. Also containing two USB drives for downloading data to a Flash Drive or directly to a printer.
