Overview
 
LS252DC Leeb Hardness Tester
LS252DC is an advanced lipstick-sized metal hardness tester which incorporates the impact device and controller into one unit. It easily fits in a pocket or your palm. It used lastest dual-coil technology which makes the tester to have extraordinary accuracy: ±6 HL and good repeatability:6HL. It adopts orientation sensors that will compensate the measurement errors in different impact directions automatically to ensure the accurate data, with OLED display screen. Equipped with impact device DC, the Leeb hardness tester is suitable for very confined spaces such as holes, cylinders or for internal measurements on assembled machines. The battery can be charged simply from USB port, also it has a customer re-calibration function.

Features

1. Direction sensor inside the probe will compensate the measurement errors in different impact directions automatically

The instrument can measure at any angles. Featuring a built-in direction sensor, the probe can automatically compensate the measurement errors in different impact directions. Multi-angle measurement is easy
 

2. Conversions to different hardness scales

LS252DC hardness tester provides a variety of hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRA/HRB/HRC) eliminating the cumbersome steps of manual table lookup

3. Integrated design, easy operation

Pen-type Leeb hardness tester is lightweight and portable with easy operation

4. High accuracy with patented dual-coil technology

Cutting-edge dual-coil technology bring the tester extraordinary measurement accuracy and good repeatability

5. Small size, easy operation

Thanks to the small size as lipstick, the LS252DC is simple to operate and easily to be carried out

6. Capable of measuring a wide range of metal materials

With 10 built-in metal materials, including steel, alloy tool steel, stainless steel and grey cast iron, the instrument can be
used in a wide range of applications and industries to meet the demands of everyday work

7. Customer re-calibration allowed

Users can calibrate the standard parts to reduce the error
