Portable Battery-Powered Printer for Hardcopy Documentation

Need a hard copy printout of your measurement results?

Our P-190 Printer with the G03-0086 Cable will allow you to print each reading as it's shown on the display. The user simply depresses the thumb switch each time they want a value transferred to the printer. Simple yet effective!

The battery-powered P-190 Printer uses standard rolls of adding machine paper, unlike thermal printers the printout will not fade over time. It is supplied with a battery charger for operation on all power worldwide.

Durometer Test Stands

AD-100 Durometer mounting in optional test stand We offer a complete line of durometer test stands. The stand, when used in conjunction with a Durometer, eliminates operator error sometimes associated with hand-held durometer testing. Our stands feature a load weight for the proper testing pressure as noted in ASTM D2240, and a quick-lock column for easy adjustment. Click here for more info on Durometer Test Stands.


Complete Kit

The DD-100 is supplied as a complete kit including the durometer, test block, instruction manual and calibration certificate in a foam-fitted metal carrying case.


DD-DB1 - Smart USB Cable

The DD-DB1 Smart USB cable connects the durometer to a computer. The output of the SmartCable Keyboard is a standard USB 2.0 keyboard signal. Connecting the SmartCable Keyboard with its built-in keyboard wedge to a computer will allow the SmartCable to be identified as a keyboard device that can send data to any Microsoft Windows application - no software wedge required. The SmartCable Keyboard will make the gauge readings appear as if they were typed in using a standard keyboard - eliminates data collection errors. If you want to collect data into a Microsoft Excel spreadsheet, simply select the cell where you want the data to appear.
