Description
Very rugged unit in an aluminum case. Note: Case color may change from the product photos. We ship either red or blue anodized cases.
NOTE: Rebound-type testers are NOT suitable for thin, lightweight parts like sheet metal, knives, bolts, nuts, washers, etc.
Please read these notes that apply to ALL Leeb-type testers from any manufacturer.
The D type probe comes standard with this device. Note you cannot exchange for another probe type.
If you are testing parts that are thinner than its capabilities, you might want to consider adding a C type probe.
Guaranteed lowest price anywhere.
We made a larger than normal volume purchase of these units to get the best price and pass the savings along to you. So this is a strictly limited time deal.
Many features that other testers don't have or if they do just some where this one has them all!!!. Advanced PC software included with bar charts, print capability, USB 2.0 interface, connect to all the options for probe types, C, G, DL etc.

I have been very pleased with the THX281 portable hardness tester. The ability to calibrate the unit is a huge advantage over the older EquoTip tester I have been using since 2001. (My order number 1108)
