DP1003 Automatic Straight Tube Kinematic Viscosity Tester

The design, manufacturing, and inspection of the EKV110 fully automatic kinematic viscosity tester comply with standards such as GB/T265, ISO3104, ASTM D445, etc. Suitable for measuring the kinematic viscosity of transparent and opaque liquids (including crude oil, light and heavy fuel oil, lubricant additives, etc.). The instrument does not require random operation by personnel. After placing the oil sample, the operator sets the oil sample number and position, and starts the test to fully automate the automatic injection and testing. The operation interface is simple, and the system has the advantages of self checking, self diagnosis, and fault prediction.

The instrument consists of three main components: a testing host, a vacuum servo box, and a cleaning servo box; The main components of the instrument are made of imported materials, and the key components are made of imported components, making the instrument more stable and reliable.

The instrument adopts a hardware system consisting of an industrial control computer and a microcontroller. The microcontroller is used to achieve constant temperature control and viscosity testing, with high real-time performance and more accurate test results. The industrial control computer is used as the overall system control, making the instrument more reliable. The industrial control computer has 1GB of memory and 4G of hard disk, which not only runs fast but also has a large data storage capacity. Adopting the Windows XP operating system and a fully Chinese interface (which can be replaced with an English interface), it is convenient for users to operate and provides multiple communication interfaces (RS-232, USB, RJ-45, etc.). It can connect to LIMS system and browse the Internet through LAN.

The operation interface consists of a TFT LCD display screen, touch screen, metal waterproof keyboard, and trackball.

Single constant temperature bath, dual viscosity meter design, constant temperature range: 20 ℃~100 ℃, adjustable throughout the entire range.

The measurement range of kinematic viscosity is wide, and each viscometer is designed with three detection bubbles, with a viscosity measurement range of 100 times. The instrument includes two viscometers, each of which is calibrated using American Keneng kinematic viscosity standard oil before leaving the factory. The instrument system software itself also has calibration function, and users can calibrate using standard oil. The viscometer uses two types of viscometers (thermistor detection method and photoelectric detection method), making the detection range wider.

The automatic injection system is equipped with two injection trays, each with 12 injection holes. Users can load 24 oil samples at once for testing; Each injection tray can be preheated, with a maximum preheating temperature of 70 ℃.

● Instrument testing process: The sample is manually placed on a tray - tray automatic injection - automatic sample searching - automatic sampling - automatic constant temperature immersion - automatic viscosity testing - automatic cleaning - automatic drying, and then the next sample is automatically made, repeating the above automatic testing process.
