RHL-140 Dual Bin Dustproof TFT LCD screen Leeb Metal Hardness
Tester Functional features: - Multiple language switching between Simplified/Traditional Chinese,
English, and German, with menu based operation.
- Adopt a proprietary dual bin dustproof design to ensure that the
main engine bin is not affected by dust;
- Type-c USB and RS485 communication interfaces can easily connect
PCs, industrial control computers, or PLCs;
- The main interface displays two hardness scales.
- There are three modes switching on the main interface (histogram
mode, full hardness mode, and curve mode).
- The production batch number setting function allows for
self-numbering of measured workpieces, facilitating statistical
recording.
- Browse for any hardness scale conversion of status measurement
data, which is convenient and fast.
- It can be equipped with 7 different impact devices, which do not
require recalibration during replacement and can automatically
identify the type of impact device.
- Support the measurement of multiple hardness systems and three
strength values.
- Built-in domestic and foreign hardness conversion tables to meet
the different needs of customers.
- It can store 510 files, with 46 to 215 groups of single measurement
values, average values, measurement dates, impact directions,
times, materials, hardness system, and other information for each
file (32 to 1 impact times).
- The upper and lower limits of hardness values can be set in
advance, and automatic alarm will be given when the limit is
exceeded, facilitating the needs of users for batch testing.
- Indication software calibration function.
- Built-in high-performance lithium battery and charging control
circuit, with a battery capacity of 2000mA.
- Computer software can be equipped to support data query, storage,
statistics, histogram display, and other functions, and stored in
Excel format
