Overview
DH40-10 Low Temperature Circulating Bath provides a precise thermostatic, hot and cold controlled standard environment for laboratory testing and analysis research institutions, which can be used as a cold source and heat source for direct or indirect heating and cooling. The product has 0.01 ° C high resolution ， +/- 0.05 ° C temperature fluctuation, which is the right assistant of 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, and the correction resolution is as high as 0.001 ° C.
2. Strong Temperature Stability: PID temperature control can automatically adjust parameters according to different media, and special needs can be manually adjusted.
3. Safety lock: Software digital lock Control system settings to avoid misoperation.
4. Fast and stable: Accurate temperature control makes the temperature in the Tank stable quickly.
5. Refrigeration system: using an effective fully enclosed Compressor for refrigeration, with fast cooling speed and multiple protections such as overheating and overcurrent.
6. Circulation system: professional domestic circulation makes the temperature uniform and stable; it can be changed to an external circulation system to establish a second thermostatic field outside the machine or as a cold source to chill down the experimental container outside the machine.
7. Alarm system: with over-temperature protection, over-temperature alarm, can set over-temperature alarm temperature, over-temperature can automatically cut off the load.
Optional RS232 or RS485 interface.
Principle
Thermostatic bath with automatic thermostatic Control system, combined with PT100 temperature sensor and PID algorithm, precise adjustment of cooling and heating units to achieve rapid temperature stability in the Tank. Domestic circulation system to ensure uniform temperature in the tank, can also be through the external circulation pump thermostatic liquid output, establish an external thermostatic field or provide cold source.
Applications
Laboratory testing, analysis and research institutions
Steps
1. Turn on the power supply.
2. Set the target temperature and over-temperature alarm temperature as required.
3. Start the device, and the system will automatically control the temperature and quickly stabilize to the set temperature.
4. You can choose to use domestic circulation or external circulation mode.
5. After the experiment, press the "Power" button to turn off the function of the instrument, but the instrument still shows the natural rise and fall of the temperature in the tank.
Notice
Please read the instructions carefully before use.
• Ensure equipment is placed in a smooth, well-ventilated environment.
• Choose the appropriate circulation mode (domestic circulation or external circulation) according to the experimental needs.
• Pay attention to the setting and activation of the over-temperature alarm function to ensure safety.
• Non-professionals should not modify the system lock parameters at will.
• When the equipment is running, do not block the ventilating port.
• Regular maintenance to ensure equipment performance.
• The heating tank model does not have a refrigeration system, please pay attention to the distinction.
