Host Machine Features:

◎Using a high-definition LCD liquid crystal display, users can enjoy intelligent operation according to the prompts on the screen. Chinese character prompts and quantitative indicators are given during each operation.

◎Powerful data processing capabilities, can automatically submit the average, final value or peak value of the tested glue sample for you.

◎Powerful data query ability, can automatically store the test values ​​of 50 units, and each unit can store 50 data.

◎Provide four sampling measurement modes: single step, hold, loop, and automatic, making your operation more convenient.

◎Automatic measurement mode can help you obtain the freezing intensity value faster, more accurately, and closer to the actual situation.

◎Set the sampling speed freely; 0.1mm/s-5mm/s. Select high-speed measurement, without the probe pressing into the rubber surface depth error.

◎Sampling depth can be preset arbitrarily (1mm—-75mm).

◎The instrument provides two kinds of sampling results, with different test combinations of sampling speed and sampling mode, it can submit the final value or peak value for the user.

◎Professional high-precision pressure sensor.

◎Professional high-precision pressure sensor.

◎One-key lifting of the test platform, saving test time and improving test accuracy.

◎High-precision mechanical transmission and equipped with 4-level anti-vibration design.

◎Users can verify the measurement accuracy of the instrument itself. (Use standard weights)

◎Automatically correct nonlinear errors, automatic fault diagnosis and alarm, automatic over-range protection, automatic error correction prompt.

◎Two-level authority management, password login.

◎Embedded micro printer, standard serial printing thermal needle is optional.

◎The USB output interface can be selected for convenient storage of experimental data.


Main features:

  • The constant temperature water tank and the refrigerator form a precise constant temperature cold water bath system.
  • A magnetic water pump circulating water flow uniform heating system is adopted, and the temperature of the water bath is uniform.
  • High-precision temperature sensor with small linear error and high temperature measurement accuracy.
  • Fully automatic frequency conversion control technology, intelligent temperature control, high temperature control accuracy.
  • The refrigerator adopts high-reliability and high-power new compressor for refrigeration, with fast refrigeration speed and low noise.
  • The temperature can be preset at will; the preset value and real-time value can be displayed in time-sharing.
  • Automation, automatic detection, automatic diagnosis, automatic alarm.
  • The inner tank of the constant temperature water tank is made of high-quality stainless steel, with a wide temperature control range and a beautiful appearance.
