3、 Product features:

1. Adopting high-precision, LCD display temperature controller, the temperature control accuracy reaches ± 0.1 ℃.
2. Adopting a hard glass cylinder with a temperature resistance of up to 180 ℃ and an insulated outer cylinder (referred to as a double cylinder), the insulation performance is good, and the sample observation is clear.
3. Adopting a desktop and all-in-one design, the instrument has good overall integrity and is easy to use.
4. Using an electric stirring device, the temperature inside the bathtub is uniform.
5. Fully spray treated, durable and long-lasting; Double layer cylinder structure, high-precision temperature controller, temperature control accuracy up to ± 0 1℃； High temperature, type.

6. Double layer constant temperature bath: The inner layer adopts a hard high-temperature glass cylinder with a diameter of 300mm × 300mm, and the outer insulation sleeve is an organic glass cylinder with a diameter of 360mm × 285mm. There is an air insulation layer between the inner and outer layers. During the test, in order to prevent water vapor from entering the insulation layer and affecting the observation, dry air can be filled into the insulation layer (the inflation equipment is provided). There are three holes on the bathtub cover, which are used to place capillary viscometer clips and adhesive wood covers. There are three adjustment screws installed on the clamp to adjust the verticality of the capillary viscometer.
7. The lighting adopts 220V energy-saving lamps, providing a guarantee for clear observation of the readings of the capillary viscometer.
8. Temperature controller:
⑴ Temperature sensor: Industrial platinum resistance, with a division number of Pt100.
⑵ Temperature controller: Intelligent temperature controller with PID self-tuning and four position dual LED window indication function, fast temperature control, fast response, small overshoot, and temperature control accuracy of ± 0.1 ℃.
⑶ Heating system: 1000W and 600W dual electric heating tubes for heating. At the beginning of the instrument's operation, 1000W auxiliary heating and 600W temperature controlled heating are used together to heat up quickly; Near the set observation temperature point, the heating power can be automatically adjusted, with 1000W auxiliary heating turned off and only 600W temperature controlled heating working to ensure stable bath temperature.
9. Mixing system: The electric mixer is a single-phase asynchronous motor that mixes evenly and controls the temperature to meet the technical specifications.
