RHT50-32-LD is high throughput, automatic 32-sample Rockwell hardness testing system for high throughput new alloy development and process optimization. The station integrates a Rockwell hardness tester probe with XY stage, 32-sample station, and laptop remote control. It enables quick, easy, and accurate hardness testing of samples 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 from 19 - 70 HRC (35 - 1000 HV).SPECIFICATIONS Features The high throughput Rockwell hardness testing system consists of: Hardness tester probe with 50 N test load for 19 - 70 HRC (35 - 1000 HV) test Hardness tester probe holder and triggering mechanism XY stage system and its control box 32-position sample stage Laptop with pre-installed control and analysis software The automatic operation improves efficiency, reduces time, and minimizes operator related error Fast, automatic hardness testing and analysis of 32 samples (~20 min), and automatic output of hardness data via a USB port The hardness testing system can be upgraded with 1D line scan and 2D mapping scan features at extra cost Please contact MTI for system customization, such as sample stage with different dimensions, integration of the station with a glove-box, etc 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 Probe A tester probe with 50 N test load is included for 19 - 70 HRC (35 - 1000 HV) test Measuring time: ~5 - 10 sec USB interface for test data output and remote control A digital camera with a laser pointer is integrated for indicating the hardness testing spot on the sample surface and recording the testing spot by saving the image XY Stage Touch screen controlled XY stage for precise sample positioning and measurement repeatability Hardness measurement time, X- / Y- axis travel speed, sample selections can be configured on the touch screen 32-sample stage with 26 mm cavities is included for testing cold embedded alloy samples 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 Operation Temperature 0 - 40
