EQ-RHT50-LD is a portable hardness tester using Rockwell static test method, in which a diamond indenter is forced into the sample and the indentation depth is automatically analyzed to determine the hardness. This tool enables direct, fast, and accurate measurement of sample hardness without the need of material-dependent calibration. The measured HV hardness can be automatically converted to HB, HRA, HRB scales. A 50 N test load probe is included for hardness tests ranging 19 - 70 HRC.

SPECIFICATIONS

Components	The portable Rockwell hardness tester includes   1 tester probe with 50 N test load for 19 - 70 HRC  test   1 carrying case with operation manual, certification, and standard test block   1 laptop with pre-installed testing software
Test Method	Portable Rockwell static test method: a diamond indenter is forced into the sample and the indentation depth is automatically analyzed to determine the hardness. The indentation depth is continuously measured while a load is applied and released. From the depth difference between pre-load and total load conditions (See the first photo below), sample hardness is determined Compared to traditional rebound and ultrasonic hardness testing method, TIV method does not require Young's modulus calibration for different materials, enabling direct, fast, and accurate measurement of sample hardness
Probes	A tester probe with 50 N test load is included for 19 - 70 HRC test Measuring time: ~5 - 10 sec Probe size: 115 mm H x 40 mm Dia. For measuring very small/thin samples, a measuring clamp fixture is included USB interface for test data output and remote control
Testing Software	Automatic hardness conversion according to DIN 50157, ASTM E140, ISO EN 18265 standards Six hardness scales: HRC (default), HV, HB, HRA, HRB scales
Sample Requirement	Sample thickness: > 1 mm Sample size: > 1 mm Dia. Sample weight: no restriction Sample surface roughness: < Ra 2.0 um For high throughput preparation of sample surface, please choose MTI's 16-Sample Automatic Polishing Machine Unipol-1500-S16
