Precision Metal Hardness Testing from Any Angle
The LS251D is a portable digital Leeb hardness tester designed for accurate and versatile measurement of metal materials. Featuring an advanced D-type impact device and a digital probe with a built-in orientation sensor, it delivers reliable results with ±6HL accuracy at any angle up to 360°. Its ability to convert between multiple hardness scales (HL, HV, HB, HS, HRA, HRB, HRC) makes it an essential tool for quality control, material inspection, and field testing.
Key Features
- High-Precision Digital Probe: Utilizes advanced digital technology for superior accuracy and stability.
- 360° Measurement Capability: A built-in orientation sensor automatically compensates for gravity, allowing for accurate readings in any direction.
- Multiple Hardness Scales: Easily switch between 7 different hardness scales (HL, HV, HB, HS, HRA, HRB, HRC) and measure tensile strength (σb).
- Quality Control Function: Set upper and lower limits to quickly determine if a material meets qualification standards.
- Statistical Analysis: Automatically calculates the maximum, minimum, and average values from the last 9 measurements.
- User Calibration: Allows users to calibrate with a standard block to eliminate measurement errors.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
