measurement microscope: measurement microscope has three sets of observation grinding system, each set of measurement system can be separately measured, and stored in the computer long-term preservation; The first set uses the eyepiece for observation, the second set uses the microscope's own screen for speckle observation, and the third set is to take photos of the speckle and observe the data on the computer monitor through measurement software; The microscope carrier can perform X and Y readings in both directions. At the same time, the Japanese Sanfeng digital differential reading counter is used to measure the data and the measurement accuracy is 1 μm. The measurement microscope fully meets the requirements of the latest version of the international diesel lubricating high-frequency reciprocating test machine method(HFRR),(standard number: ISO 12156.1-2018) for measuring microscope method A.

compression mechanism cold constant temperature system:
(1) The cold constant temperature and humidity system with compression mechanism has the obvious advantages of fast refrigeration speed and high efficiency. At the same time, it is an independent control unit. The selection of a temperature constant humidity box with appropriate specifications can be used to control the temperature and humidity of other instruments. The control accuracy is 0.1. The instrument is automatically controlled throughout the entire time. After the customer sets it, the instrument executes the equipment order and controls the temperature and humidity in the box.
(2) Operating ambient temperature(in the test host box): 0 to 50 °C, control accuracy 0.1 °C; The factory setting is 23 ± 0.1 °C, and customers can also set up their own according to actual needs. Operating environmental humidity(in the test host box): 5-95 % R.H. range adjustable, display accuracy 0.1; The factory setting is 53 % ± 1 %, and customers can also set up their own according to actual needs.
(3) Compression mechanism cold constant temperature and humidity system: This system consists of a constant temperature and constant temperature and humidity control instrument. The two parts use a split type connection to avoid the resonance of the test machine mechanical system due to the high frequency vibration of the compressor and gas pump.
(4) The system fully meets the requirements of the latest version of the international diesel lubricating high-frequency reciprocating test machine(HFRR),(standard number: ISO 12156.1-2018 ASTM D6079-2018) for test temperature and humidity control
