Leeb Hardness Tester THL280 PLUS

Product overview:

THL280plus is an innovative improvement in hardness measurement mechanism and circuit performance. Low power design, connect computer, data exchange, mass storage (600 groups). No less than 100 hours of standby time, AA No. 5 ordinary battery power supply, easy to carry, more flexible replacement. It is especially suitable for work site and field operation, and for the needs of users at home and abroad.

Features

LCD display of 128×64 matrix with back-light, showing all functions and parameters.

Converts to all common hardness scales (HV,HB,HRC,HRB,HRA,HS).

English displaying and easy and convenient menu operation.

Powerful PC Software available and USB 2.0 interface & with the USB Protective Membrane.

7 types of Impact Device optional, which don't need to be recalibrated when changing them.

Memory of 600 groups dataimpact times:321.Lower limit setting and sound alarm.

Material of “cast steel” is added; HB values can be read out directly when D/DC impact device is used to measure “cast steel” work piece.

Printer be separated from main unit and copies of testing results can be printed as required.

AA battery can easy change and transport.

Inbuilt function of Software Calibration.
