Simple explanation of each model of asphalt penetration meter:

1. SZR-3 penetrometer is double digital display, semi-automatic type. Manually adjust the adjusting screw under the glass cylinder to make the test asphalt surface contact the needle slightly. Press the test button to automatically time it. When the time is up, the needle bar will be locked automatically. Manually use a digital micrometer to measure the penetration value. After A, read the micrometer.

2. SZR-5 penetrometer is a computer automatic penetrometer. The microscope adjustment method adjusts the contact between the test asphalt surface and the needle. Press the test button to automatically time, when the time is up, the LCD will automatically display the penetration value, store it, and automatically calculate the average value. Can store 10 sets of test data.

3. The penetration of SZR-6 is similar to that of type 5, and there are many heating devices, which can automatically control the temperature to be maintained at 25 ° C when the temperature is below 25 ° C

4. SZR-7 penetrometer is equipped with printer on the basis of type 6.

5. The SZR-8 penetrometer has a large screen display, which can display real-time time, and can perform three consecutive tests to automatically display the average value of the penetrability. Can be connected to a computer with test software. Microscope adjustment method to adjust up and down. Can be automatically calibrated, and the sensor will automatically alarm when it is out of range.

6. SZR-9 penetrometer has printing function on the basis of type 8.

7. SYD-2801F type is equipped with high and low temperature constant temperature water bath on the basis of type 8, which can be used for high and low temperature penetration test.
