Producteigenschappen:
◆ Germany HBM high precision force sensor, factory accuracy control at < 0.5%, better than the ISO standard of ±1%.
◆ Automatic test, can be connected to the computer to synchronize the data to the computer software, automatically generate reports and graphs.
◆ Precision ball screw drive, aluminum alloy panel, high quality copper gold-plated upper and lower pressure plate and reasonable design, ensure the instrument durable. Our professional design and programming team can also upgrade the instrument.
◆ Touch screen Chinese display, friendly man-machine interface operation. Complete the test automatically, with the test data statistical processing function, micro printer output, can also be connected to the computer operation. When connected to the computer, in addition to automatically storing the results, the pressure-resistance curve can be displayed and saved.
◆ High performance stepper motor and Silicon Labs high performance chip control ensure accurate transmission, fast and efficient testing.
◆ The calibration procedure is specially set inside the instrument, which is convenient for the measurement and calibration department (third party) to calibrate the instrument. When calibrating, enter the calibration test program, place the standard sensor between the upper and lower pressure plates, and the indication error can be easily calibrated.
