Quote Contact_cs@roasexpo.com

-Main functions and features
It is widely used for soft and hard metals, non-ferrous metals, and non-metals.
It is an easy-to-operate and high-precision testing machine that can perform quick tests.
The traces of the test are fine, so the processing of the test piece by applying the reference load and the test load.
It has the advantage of preventing errors that occur depending on the condition to a minimum,
and the principle of operation is to apply a certain super load and add a test load to it to digitally measure the difference in depth between the super load and the test load. It is a testing machine that can perform tests based on ISO regulations.

1. Improve the difficulty of the existing direct correction
   (Calibration procedure according to ISO regulations)
   (Super load, pressurization time, holding time, return time arbitrarily set)

2. Adopt large L.C.D
   *Various conversion functions
   * Korean-English conversion, SI unit conversion (kg, N) , other hardness values ​​conversion
   * 15 or more scale selection, conversion function
   * Designation of number of tests (1 ~ 99)
   *Standard deviation, mean value
    (Function to display all test data on the screen)
   * Automatic calibration of round bar samples

3. Auto pressurization of test load after super-load pressurization

4. Load is automatically recognized as error/normal by selecting the rotary lever and setting the load value suitable for the scale

5. Permanent life is guaranteed by the adoption of the front keypad.

6. Incredible reproducibility for repeated measurements.

7. PC scalability with RS-232 output.
