The NewSonic SONO-G Handheld Leeb Probe with G Impact Device is for hardness testing applications involving heat treated, non-heat treated, and heavy components.
By adding a Leeb G hardness tester probe to its line up, NewSonic has made the SonoDur 3 a well-rounded hardness testing solution. The reference scale for the NewSonic Leeb G hardness probe is Vickers HV10 and calculates the Vickers hardness HV from the L-value per ISO 16859. The SonoDur can also calculate to other hardness scales or tensile strengths (EN ISO 18265-2014, ASTM-E 140-2013) and correlation* (HV5/HV10 to HB).
Equipped with Bluetooth
With 2.4 GHz Bluetooth technology, the NewSonic Leeb G rebound hardness tester can measure hardness immediately with wireless data transfer. The SonoDur-L app comes already installed on your SonoDur 3 if buying new, or a simple update to your existing SonoDur3 is all that is needed to begin taking measurements.
Operating Specs & Power Supply
Each NewSonic Leeb G probe will operate for over 8 hours and will work in freezing to warm temperatures ranging from 14ºF to 129ºF (-10ºC to 45ºC). Each Leeb G probe comes with a 3.7V li-ion battery that charges with a USB power supply.
