MODEL: HL-300A Hand Held Digital Hardness tester
|
Great care has been taken to ensure faultless quality standards for the electronics and mechanical components.
Demanding tolerances ensure that individual components (impact body, impact devices, standard test block and supporting rings) are mutually interchangeable without loss of accuracy
■ Functions:
Menu operation with LCD display.
Automatic detection and application of impact devices (including D, DC, D+15, DL, C, G, E).
L-value convertible to Brinell, Rockwell, Vicker and Shore.
Data acquisition and output by micro-printer.
960 data store capacity.
Data transferable to PC via RS232 or USB interface and Foresight software.
Mean value, max value, min value and standard deviation.
Reference setting (date, work-piece No. etc.).
Selection of limitation with a sound alarm.
Conversion table revision.
Measuring directions selection.
Measuring calibration.
Automatic calibrationnew
■ Applications
Hardness tests on installed machines or steel structures.
Rapid testing of multiple measuring areas for examination of hardness variations over larger regions.
In locations difficult of access and in confined spaces.
In situ on heavy and large work pieces or on permanently installed components.
Measuring hardness for produced parts at production line.
Identifying metallic material stored in a warehouse.
Ineffectiveness analysis of permanent parts, pressure vessel, turbo generator.
