UST-32 Portable Ultrasonic Hardness Tester

1. Description:

Ultrasonic Hardness Tester UST-32 applies ultrasonic contact impedance method to do comparative hardness measurement for testing pieces, with the high accuracy, efficiency, portability and easy operation. UST-32 is a high-precision portable device for quick measuring hardness of small cast material, weld inspection, heat affected zone, nitride dies and molds, thin walled parts, bearings, tooth flanks, etc. It is used for measuring the hardness within the ranges of main hardness scales – HB, HRC as well as HV. It is optimal for field, workshop or laboratory conditions.

2. Features:

-Nondestructive, no damage to work piece surfaces

-High precision, tolerance within ±1 HRC, OR ±3% for HV/HB

-Quick measuremetn. Hardness values come out within 1 sec.

-Wide measuring range, upto 1700HV

-Can be used onto thin work pieces such as chrome plated surfaces, nitrided surfaces, carburized surfaces, thin plates, thin wall pipes

-Can be used to test curved and regular surfaces like gears and crank shafts

-999 groups of data storage, each including 5 tested values.

-Data can be output to a Blue tooth printer, or to computers via a data line

-Multiple types of probe at option, including 5N type, 30N type and 4mm small dia type for tiny work pieces.
