Product description: The CT series of high-precision constant-temperature baths requires a constant temperature environment to ensure accurate and high-precision viscosity measurement! The temperature of the bathtub remains constant, with even temperature distribution throughout the entire bathtub. Its unique design ensures that the temperature uniformity across the bathtub is above ±0.01°C, providing a highly stable environment for viscosity experiments. The bathtub is designed using the dual-chamber principle along with a unique circulation system: it features a mixing chamber and a measurement chamber, whereby the liquid level in the measurement chamber remains constant despite evaporation of the bath water. 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. The temperature controller is an original imported unit, offering high-precision temperature control along with adaptive PID regulation capabilities. Safety: In addition to having a low water level alarm function and high-temperature cut-off protection, it is equipped with an air leakage protection switch to ensure safety during use. The 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, dew formation on the window glass can affect visual observation. The inner tank is designed with stainless steel to maximize its service life. Multi-station design, capable of supporting automatic or manual testing at 1–6 test stations.

Semiconductor cooling: It has a long operational life (though low cooling capacity); it can be used for constant-temperature experiments around 25°C to 50°C, and can operate continuously 24/7 throughout the year. Compression refrigeration: It can achieve high cooling efficiency, making it suitable for laboratories that operate during the day. It can also be used with other tanks that require a cooling source to create lower temperatures; it is capable of reducing 10 liters of anhydrous ethanol to sub-zero temperatures in a short time. The microprocessor of the IDS viscosity measurement station is used to control the rise and free fall of the liquid within the viscosity tube, enabling automatic and intelligent detection of the time it takes for the liquid to flow through ； By using photoelectric infrared sensors, these sensors can automatically adjust the appropriate light intensity based on the color depth of the solution being measured, thereby accommodating samples of varying color intensities ； Meanwhile, the sensor features a stainless steel outer casing made of glass fiber, offering corrosion resistance, temperature tolerance, and a long service life ； The inlet valve and PPS valve seat have the capability to resist strong acids and strong bases ； Each testing station is independent of the others, and different or the same testing methods can be used to measure different or the same samples ； 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 ； Applicable viscometer tubes: All U-type viscometer tubes, micro-Ostwald viscometer tubes, and diluted U-type viscometer tubes. Sample lifting method: Pressure method (can be customized according to the customer’s own samples). 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 measurement value. Dimensions (L*W*H): 115×90×480 mm. Testing error: 3‰ using the capillary method. The IDS main controller is the data transmission module of the automatic viscometer system; it serves as a hub for transmitting data from various individual measuring units to a PC, and it can be connected to multiple measuring units. The viscosity measurement software can calculate and display the following results: the average values for single-pass and multiple-pass measurements, as well as the deviation values using standard/absolute/percentage deviations. For the single-point method, it calculates kinematic viscosity, dynamic viscosity, relative viscosity, specific viscosity (viscosity number), intrinsic viscosity (limiting viscosity), and average molecular weight based on viscosity. The multi-point method allows for extrapolation using Fickentscher’s K value; various internationally recognized viscosity formulas are available. Single-point methods include the Sulz-Brashke equation, Hagenes equation, Solomon-Hutta equation, Billmeyer equation, Maron equation, and Martin equation. The software can import EXE files for simulation and verify the results. It is compatible with Win7, Win8, and newer operating systems. Permission management feature: 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. Measurement result storage and printing function: All recorded measurement results from each day are saved in chronological order or by measurement location, allowing the result reports to be viewed or printed at any time. Based on the set values for standard/absolute/percentage deviation, the measured results are automatically calculated during the measurement process; if the deviation exceeds the set value, the software has an automatic re-measurement function.
