Model: YTDCW-3506

Product application: The DC series low-temperature constant temperature bath is a commonly used equipment essential for laboratories. It is widely used in fields such as bioengineering, national defense, medicine, food, chemical engineering, metallurgy, chemical analysis, petroleum, etc., providing users with a high-precision, controlled, and uniform temperature constant field source. It is an ideal constant temperature bath for various research institutes, universities, factory laboratories, and quality inspection departments.

The DC series low-temperature constant temperature bath adopts SUS304 stainless steel as the overall inner liner, and the outer shell is processed and formed with high-quality cold rolled steel plate. At the same time, the electrostatic spraying process is used to improve the anti-corrosion effect, and intelligent temperature control and temperature sensor Pt100 platinum resistance are used. The heating system is composed of a high-efficiency U-shaped electric heating tube. The refrigeration system is composed of a fully efficient anti-interference compressor, evaporator, etc. The constant temperature control part adopts an internationally advanced anti integral saturation PID control system to prevent temperature surge during the heating process, thereby improving control accuracy.

Product Features

Adopting microcomputer temperature control PID adjustment high-tech, with high temperature control accuracy.

The intelligent all digital system can correct the deviation of temperature measurement values, achieving a digital display resolution of 0.1 ° C.

The refrigeration system has multiple protection functions for overheating and overcurrent.

Intelligent instrument control, simple operation, high temperature stability, with upper and lower limit overtemperature alarm function.

Adopting dual digital tube display, the measured value (PV) of the upper digital tube is red, and the set value (SP) of the lower digital tube is green, with LED display.

Equipped with anti-interference compressor.

The cooling speed is faster than similar products, with low noise and vibration.

There are internal and external circulation. During the external circulation, the constant temperature liquid in the tank can be introduced externally, which can establish a second constant temperature field. It can also serve as a cold source (heat source) to introduce the liquid in the tank externally, which can maintain the temperature of the experimental container outside the tank and expand the scope of use.
