Overview
DH20-10 Low Temperature Circulating Bath is a model of DH series laboratory Thermostatic bath, which provides 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 for direct or indirect 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
1. 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, and the correction resolution is as high as 0.001 ° C. Temperature Stability, PID temperature control can automatically set parameters, can also be adjusted manually. Software digital lock setting value to avoid misoperation.
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, so that the temperature is uniform and stable. Can be changed to external circulation system, external circulation pump can output thermostatic liquid to establish a 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.
Principle
The Thermostatic bath uses an automatic thermostatic Control system, combined with PT100 temperature sensor and PID control algorithm, to precisely adjust the heating or refrigeration power to achieve rapid, stable and accurate control of the temperature 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. The refrigeration system uses a fully enclosed Compressor to achieve rapid cooling.
Applications
All kinds of laboratory testing, analysis and research institutions
Standards
The data did not mention specific compliance criteria
Steps
The information does not provide detailed operation steps
Notice
The software digital locking function can avoid the wrong operation of unrelated personnel and ensure the accuracy of the experimental data.
* Press the "Power" button to turn off all functions of the instrument, but the instrument will still display the natural rise and fall of the temperature in the tank.
The heating tank model does not have a refrigeration system.
The instrument has over-temperature protection and alarm functions, which can automatically cut off the load when it is over-heated.
