Application areas: Suitable for testing lubricants and in pharmaceutical research and development; it meets all international and domestic standards such as GB265, ISO1628, ASTMD4603, JJG 155-2016, ISO307, ASTMD789, and pharmacopoeial standards. II. Product Description (I) The CT series of high-precision constant-temperature baths require a constant-temperature environment in order to ensure accurate and high precision in viscosity measurement! The temperature of the bath remains constant, with uniform temperature throughout the entire bath. Its unique design ensures that the temperature uniformity across the bath is above ±0.01°C, providing a highly stable environment for viscosity experiments. 1. The bathtub is designed using a dual-chamber principle along with a unique circulation system: it features a mixing chamber and a measuring chamber, the liquid level in the measuring chamber remaining constant despite the evaporation of the bath solution. The partition between the two chambers can be removed easily for routine cleaning and maintenance, and a drain valve is installed at the bottom to facilitate cleaning. 2. The temperature controller is an original imported unit, offering high-precision temperature control as well as adaptive PID regulation capabilities. 3. Safety: In addition to having a low water level alarm function and a high-temperature cut-off protection function, it also features a built-in air leakage protection switch to ensure safety during use. 4. Transparent window and lighting design allow direct observation of the inside of the bathtub as well as the testing process ； It should be noted that when the temperature is below 20°C, condensation may form on the window glass, affecting visual observation. 5. The inner tank is designed with stainless steel to maximize its service life. 6. Multi-station design, capable of supporting automatic or manual testing at 1–6 test stations. 7. Main technical parameters: Model, constant temperature accuracy, temperature uniformity, heating power, operating temperature, external dimensions in CM.

IDS-4: ≤±0.01℃, ≤±0.01℃, 1200W, operating temperature from 20℃ to 120℃; dimensions: length 85X width 28X height 56. IDS-6: ≤±0.01℃, ≤±0.01℃, 1200W, operating temperature from 20℃ to 120℃; dimensions: length 102X width 28X height 56. (II) GB265 viscosity measurement station: 1. Microprocessor for the viscosity measurement station, used to control the upward movement and free fall of the liquid within the viscosity tube, as well as to automatically and intelligently determine the time it takes for the liquid to flow through ； 2. A photoelectric infrared sensor is used; this sensor can automatically adjust the appropriate light intensity based on the color depth of the solution being measured, thereby meeting the needs of samples with different color intensities ； Meanwhile, the sensor features a stainless steel outer casing made of glass fiber, giving it corrosion resistance, temperature tolerance, and a long service life ； 3. The inlet valve and PPS valve seat have the capability to resist strong acids and strong bases. 4. Each testing station is independent of the others; different or identical testing methods can be used to test different or identical samples. 5. Precise positioning is designed and manufactured, enabling the measurement distance to be accurate to 40 mm as specified by ISO, thus ensuring the standardization of the data. 6. Applicable viscosity tube: Zhenyue GB265 standard viscosity tube. 7. A unique defoaming technology that effectively controls foaming in the liquid being measured. 8. Sample improvement method: Pressure method (can be customized based on the customer’s own samples). 9. Technical parameters: Measurement time range: 0.001–999.999 seconds; viscosity range: 0.3–5000 mm2/s; timing display resolution: 0.001 seconds; timing accuracy: 0.001 seconds or 0.1% of the measured value. Dimensions (L*W*H): 115×90×480 mm. Testing error using the capillary method: 3‰. The IDS main controller serves as the data transmission module for the automatic viscosity tester system; it acts as a hub that transfers data from various individual measurement units to the PC, and it can be connected to multiple measurement units. (IV) Viscosity measurement software: 1. It can calculate and display the following results: a) The average value of the time for a single passage and multiple passages; b) Comparison deviation method: standard/absolute/percentage deviation; c) Single-point method: kinematic viscosity, dynamic viscosity, relative viscosity, specific viscosity (viscosity number), intrinsic viscosity (limiting viscosity), and average molecular weight based on viscosity; d) Extrapolation using multiple points; e) K value according to Fickentscher; f) A variety of internationally recognized viscosity formulas are available; g) Single-point methods (Zulz-Brashke equation, Hagenes equation, Solomon-Huhtala equation, Billmeyer equation, Maron equation, Martin equation). 2. The software can utilize EXCEL simulations to verify the results. 3. It is compatible with Win7, Win8, and later operating systems. 4. Permission management function: Operators must use the software with their own account and password, and access to the system is restricted based on the level of authorization they possess. 5. Measurement result storage and printing function: All measurement results recorded on a daily basis are saved in chronological order or by measurement location, allowing for the viewing or printing of result reports at any time. 6. It can automatically calculate the measured results during the measurement process based on the set values for standard/absolute/percentage deviation; if the deviation exceeds the set value, the software has an automatic re-measurement function. (V) Cleaning module (optional module): 1. Each set of cleaning modules can be connected to two testing tables. 2. It is also possible to configure two types of cleaning solutions. 3. The cleaning method involves automatically adding cleaning solution, after which the liquid is allowed to flow up and down inside the viscosity tube to carry out the cleaning process. 4. It is equipped with a built-in suction pump for liquid recovery, which can draw out the liquid from the viscosity tube and collect it in one place. 5. When in use, it can be installed on the sink; it is small in size and does not take up much space
