Automatic kinematic viscosity tester

summary:

According to the requirements of gb265 / T and GB / t1632-93, this instrument is used to test the kinematic viscosity, viscosity number and characteristic viscosity number of oil and polymer dilute solution. It is widely used in Pharmacopoeia, petroleum, chemical industry, scientific research, metrology and other departments.

Technical parameters:

The controller adopts high-speed CPU; ± 18bit multi integral high-speed and high-precision ad; the hardware circuit design is unique with chip technology; the input and output interface board adopts contactless solid-state relay, which is integrated with the controller; the whole machine has no adjustable potentiometer, which has high reliability and high measurement accuracy.
The original imported 5.0-inch 480 × 272 pixel true color TFT LCD is adopted for the display screen, with fine graphic display, no sawtooth, gorgeous color and high display resolution; the plastic injection integrated display screen frame is beautiful and elegant; the full Chinese operation interface makes the display intuitive. At the same time, it has authority management function, which can effectively avoid non professional personnel setting the key parameters of the tester.
L use human body inductive touch button, no mechanical contact, dustproof and waterproof, anti radio frequency interference, long service life.
High precision clock of ± 5ppm and built-in battery are adopted to ensure that the external power failure data can be stored for 5-8 years.
Using imported PT100 sensor, the temperature measurement is fast and accurate.
The embedded thermal printer makes the printing more quiet, fast and clear.
The whole machine has strong anti-interference ability.
Unique photoelectric detection circuit, fast and accurate detection, completely avoid false detection and missed detection.
It can be used to measure two kinds of samples asynchronously at the same time.
Users can choose refrigeration equipment to measure low temperature viscosity.
L Ubbelohde viscometer and countercurrent viscometer (specifications are selected by users)
The user can set parameters according to the actual situation, which can quickly calculate the measurement results and errors. If the measurement results are out of tolerance, the tester will automatically re measure until the error requirements are met.
