Series Full Automatic Engine Oil Apparent Viscosity Tester (CCS)

Applicable standard
ASTM D5293

Performance characteristics

1. This instrument is suitable for measuring in the range of -5 ~ -35 ° C, the shear stress is about 50,000 ~ 100000 Pa, the shear rate is 105 ~ 104 S-1, the viscosity is 1500 ~ 27000 mPa • s (national standard automatic instrument Apparent viscosity of engine oil in the viscosity range of 2800 to 18000 mPa•s).
2. The external structure of the instrument is split type, which avoids the impact of the vibration generated by the compressor on the rotor and test results.
3. The instrument integrates automatic sample injection, temperature control, detection, calculation, storage and printing, and realizes automatic unattended operation.
4. 7-inch color LCD touch screen display, full Chinese operation interface. Various parameters and working status are visually displayed.
5. The 510-channel automatic sample introduction system can automatically measure 10 samples at a time (each of which can be repeated according to the set number of times, no need to change samples in the middle). The entire experiment process does not require personnel to be on duty.
6. imported compressor cascade refrigeration, imported refrigerant. Automatically control sample temperature and cold bath temperature.
7. Imported by imported motor, the imported tachometer has high precision and strong stability. Motor operating current fluctuation <1mA (national standard requirement <5mA).
8. The 8-turn stator positioning system is a utility model patent (patent number: ZL201621453512.4).
9. No solvent cleaning required.
10. The test is automatically stopped and warmed up to facilitate rapid cleaning.
11. instruments with LIMS system function is optional
12. PT-D5293-005N without sampler, PT-d5293-005N1 with One-channel four-column automatic sampling system, PT-D5293-005N10 with Ten-channel automatic sampling system
