Automatic Petroleum Products Kinematic Viscosity Tester

MOEORW-WEL94 Kinematic Viscometer (Automatic Petroleum Kinematic Viscosity Tester) complies with GB/T265-1988 national standard. Adopts fuzzy PID temperature control and 4-channel parallel testing to automatically calculate kinematic & dynamic viscosity of Newtonian petroleum liquid. Built-in GB intelligent algorithm supports dual modes: fast rough test & standard precise test, suitable for mass inspection of oil factories and single-unit test in small labs.

For testing all liquid petroleum products: lubricating oil, diesel, fuel oil, power insulating oil, hydraulic oil, gear oil, etc. Target customers: lubricant manufacturers, CNAS third-party labs, petrochemical plants, power quality inspection departments, auto repair testing stations, university chemical labs, instrument distributors.

1.National Standard Compliance
The full test flow of this Automatic Petroleum Products Kinematic Viscosity Tester complies with mandatory standard GB/T265-1988. Built-in program automatically restricts irregular operations: minimum flow timing locked at 200s, and 350s for 0.4mm thin capillary tubes. Timing rounds can be switched between 1~4 times. When testing 3 or 4 rounds, the machine automatically identifies and eliminates out-of-tolerance timing values and calculates valid average values, fully meeting GB requirement that timing deviation between 15~100℃ shall not exceed ±0.5% of average value without manual calculation. Temperature control and timing components are metering-grade accessories. Matching capillary tubes support full verification solution from metrology institute, and all test reports are legally valid. Bulk purchase can be directly applied for laboratory qualification assessment and bidding projects.

2.High-precision Constant Temperature
This Full-Automatic Kinematic Viscosity Water Bath Tester adopts advanced fuzzy PID temperature control technology, officially calibrated temperature accuracy ±0.02℃, far better than ordinary water bath error of ±0.1~0.5℃ on the market. Temperature range: ambient temperature ~150℃, with 5 preset standard GB temperature points: 20℃, 40℃, 50℃, 80℃, 100℃. Custom temperature higher than ambient temperature is available with 0.1℃ setting resolution. Professional basis: Kinematic viscosity is highly sensitive to temperature; 0.1℃ fluctuation causes 1% viscosity deviation. ±0.02℃ high precision minimizes system error. Built-in GB standard constant temperature countdown enforces standard holding time: 10min at 20℃, 15min at 40/50℃, 20min at 80/100℃ to avoid distorted data from insufficient temperature holding.

3.4-Channel Parallel High-efficiency Testing
This Oil Capillary Viscosity Detector is equipped with 4 independent viscometer holes. Four capillary tubes can start/stop synchronously without mutual interference. Each channel supports 1~4 cycle timing rounds. 1~2 rounds work as rough test mode for quick viscosity estimation of unknown oil samples; 4 rounds are GB precise test mode with automatic outlier elimination, balancing testing efficiency and data accuracy.

4.Large-capacity Data Storage + Automatic Printing
MOEORW-WEL94 Kinematic Viscometer is equipped with large-capacity storage chip to save 2000 complete test records. Each record includes sample ID, test temperature, constant temperature holding time, capillary tube diameter & constant, four original timing values, final kinematic viscosity, test date & time. Embedded panel thermal printer automatically outputs full paper test reports after test completion, no external computer required.

5.7-inch Intelligent Touch Control Operating System
This Automatic Petroleum Products Kinematic Viscosity Tester is fitted with 7-inch HD color touch screen and full Chinese visualized interface, divided into three core menus: Test, Preparation, Data Record. Visualized operations include one-click temperature control switch, viscometer parameter input, printer enable/disable, system time calibration and timing round adjustment. Abnormal single timing data can be deleted independently. Operators with zero professional background can finish full test procedures within 10 minutes.

6.Industrial Safe & Durable Structure
This Full-Automatic Kinematic Viscosity Water Bath Tester is built with multiple industrial protections for long-term intensive mass testing. Built-in anti-dry burning program locks heating function without bath liquid to prevent heater burnout. Split design of main unit and bath cover with separate wiring, equipped with cooling fan and independent fuse box, supporting wide voltage AC220V±5% to fit unstable factory power supply in China. Wearing parts including temperature sensor, print head and fuse share unified specifications; spare consumable packs can be provided with bulk orders. Operating environment range: 5~35℃, humidity 10%~80%, stable operation for labs in northern & southern regions of China.

7.Complete Set of Standard Accessories and Customization Services
The factory standard configuration includes capillary viscometers in various sizes (0.8/1.0/1.2 mm available), bath clamps, rubber suction balls, a list of cleaning solvents, an instruction manual printed entirely in English, and an individual factory calibration certificate for each instrument. OEM and ODM Customization Support: Custom screen-printed logos on the housing are available, with low minimum order quantities to facilitate distribution under independent brands. Custom built-in test programs tailored for the lubricating oil, insulating oil, diesel, and fuel oil industries can be provided. With a rated power of 1,600 W and standard 220 V commercial and industrial power supply, no electrical modifications are required in either new or existing laboratories; the unit is ready for installation and use upon delivery.
