Very rugged unit in 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 light weight 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 fro 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.

Device conforms to the Standard ASTM A956-02 & DIN 50156 .
