Overview
DH20-15 Low Temperature Circulating Bath is one of the BINGLIN brand DH series products, providing a precise thermostatic, hot and cold controlled standard environment for various laboratory testing and analysis institutions, and can be used as a cold source and heat source directly or indirectly heating and cooling. This model has 0.01 ° C high resolution ， +/- 0.05 ° C temperature fluctuation, which is a good right-hand assistant for laboratory personnel.
Features
Automatic thermostatic Control system: Using self-developed temperature control technology with PT100 and all imported electronic components, the software system is convenient to correct the error between the displayed temperature and the actual temperature (resolution up to 0.001 ° C), PID temperature control can automatically or manually adjust parameters, digital lock settings to prevent misoperation, accurate and fast temperature control.
2. Refrigeration system: using an effective fully enclosed Compressor for refrigeration, with fast cooling speed and multiple protections such as overheating and overcurrent.
3. Circulation system: with professional domestic circulation to make the temperature uniform and stable, and can be changed to external circulation system, external circulation pump can output thermostatic liquid to establish the second thermostatic field outside the machine or as a cold source to chill down the experimental container outside the machine.
4. Alarm system: with over-temperature protection, over-temperature alarm function, can set over-temperature alarm temperature, over-temperature can automatically cut off the load.
Optional RS232 or RS485 interface.
6. Press the "Power" button to turn off all functions of the instrument, but the instrument can still display the natural rise and fall of the temperature in the tank.
Principle
The Low Temperature Circulating Bath uses an automatic thermostatic Control system combined with PT100 temperature sensor and PID control algorithm to precisely adjust the working state of the refrigeration system (fully enclosed Compressor) and heating system to achieve fast and stable control of the temperature of the medium in the Tank. The domestic circulation system ensures uniform temperature in the tank, and the external circulation function can pump out the thermostatic medium to provide a stable temperature environment for external experiments.
Applications
Laboratory testing, analysis and research institutions
Notice
The heating tank model does not have a refrigeration system.
* The load can be automatically cut off when overheating, but users need to set the over-temperature alarm temperature according to their needs.
The software digital locking function can avoid the wrong operation of unrelated personnel and ensure the accuracy of the experimental data.
Optional RS232 or RS485 interfaces are available to meet different communication requirements.
