• low-temperature constant temperature bath
  • DH-0520
  • low-temperature constant temperature bath
  • Temperature range: -5°C to 100°C, Capacity: 20L
DH-0520 low-temperature constant temperature bath adopts an internationally advanced fluorine-free refrigeration system. It is a low-temperature experimental instrument developed for scientific research, biology, medicine, chemical and other departments with high requirements for constant temperature accuracy. It has the characteristics of making the temperature inside the bath more precise, uniform, and intelligently controlled. It has an over-temperature alarm system to ensure the safety of the instrument and a power-off protection function that can be automatically delayed for three minutes. The cooling liquid in the bath can be externally drawn, and the cooling machine can also be used as a normal thermometer and other temperature measuring instrument for calibration in manufacturing.

Product Features
1. Fully enclosed imported compressor with low refrigeration system noise;
2. 7-inch touch screen with an inclined design displays temperature, time, and other parameters, which can be seen clearly from a distance;
3. Customers can set it so that the parameters remain unchanged after power-off, and the instrument will start working by default when power is turned on;
4. The internal and external circulation can be switched, and the pump flow rate can be controlled, suitable for various experimental needs;
5. The system adopts internationally advanced fluorine-free and environmentally friendly refrigeration technology;
6. Working time can be timed, and the instrument will stop working after the set time has elapsed;
7. Temperature fluctuation is ±0.1℃;
8. The refrigeration compressor has automatic protection functions such as overheating and overload.
