This constant temperature circulator is a new type of equipment specially produced according to the needs of material analysis and production inspection in industries such as petrochemical and chemical fiber plastics. This machine is composed of a constant temperature bath host and a cooler, which is not affected by environmental temperature. It does not have the trouble of external cooling water and short lifespan defects of semiconductor refrigeration, and can easily obtain a constant temperature value below room temperature. The front and rear of the host are equipped with large flat viewing windows, which can accommodate four capillary viscometers in a row, suitable for Ubbelohde, Austenitic, Pinkers viscosity testing and other physical and chemical experiments.

Product features:
1.4.3-inch TFT color large screen display with an accuracy of 0.001, multiple interfaces can be freely switched, and the machine's set temperature, actual temperature, liquid level, heating, cooling, rotational speed, running/stopping and other operating states can be displayed on the screen;
2. Compact appearance, small size, very convenient to place on the desktop;
3. Suitable for various capillary viscometers and capable of conducting multiple sample tests simultaneously;
4. Two point calibration function, which can conveniently calibrate the temperature of two temperature points;
5. Level IV PID control, temperature stability ± 0.01, temperature uniformity ± 0.01;
6. Third level security protection:
First level low liquid level protection, when the liquid level is low, it reminds the user that they can add liquid and stop the machine when there is no liquid added after waiting;
The second level of adjustable hardware safety temperature protection can timely cut off the power supply of the heater during dry burning;
The third level can set high and low temperature limits. When the detected temperature exceeds the set value, an alarm and shutdown will be triggered. Various alarm codes will be displayed directly, and the error point can be directly determined. When an alarm is triggered, the buzzer can be set to be silent or audible;
7. Built in maintenance free pressure/suction pump circulation pump, capable of internal and external circulation, with strong pump power. The pump can simultaneously stir the bath liquid in the tank in both horizontal and vertical directions, with good temperature uniformity in the tank. It can be used for internal and external circulation applications. When the machine is placed on the ground for external circulation, testing can also be conducted on the desktop;
8. The pump pressure and flow automatically adapt to external loads, and the international standard M16x1 connecting nut can be configured with different joints to meet the needs of different external circulation pipe diameters;
9. The parts in contact with liquid or steam shall be made of high-performance stainless steel and high-performance plastic, which are corrosion-resistant and free from scale formation;
10. Multiple operation modes are available, and accidental power outage can be automatically restored.
