Overview
TENLIN GDH-2020 High Accuracy Low Temperature Circulating Bath is a precision temperature control device with a Temperature range of -20~ 100 ° C and a Tank volume of 20L. It uses an advanced Refrigeration and Control system designed to provide laboratories with high Stability and high uniformity in a thermostatic environment.
Features
1. Low Noise Air-Cooled Fully Enclosed Compressor Unit, Fast Cooling Speed and Strong Temperature Stability.
2. Control system adopts self-developed special software and High Accuracy Pt100 Sensor, with imported electronic components, accurate temperature control.
3, with internal and external circulation system. The external circulation can establish a second thermostatic field or as an external cold source; domestic circulation to ensure that the liquid temperature in the tank is highly uniform and stable.
4, Equipped with a complete Safety protection system, including refrigeration overheating/overcurrent protection, over-temperature sound and light alarm, over-temperature automatic load cutting and other functions.
5. Adopting a large liquid crystal control instrument, it is easy to operate and supports automatic search or manual adjustment of P.I.D. parameters.
6. Temperature correction accuracy up to 0.01 ° C, Temperature Fluctuation up to +/- 005-0.01 ° C (depending on the model).
Principle
The device reduces the temperature of the medium in the tank through a fully enclosed Compressor refrigeration system. The Control system monitors the temperature in real time through the High Accuracy Pt100 Sensor and precisely adjusts the refrigeration power using the PID algorithm to achieve fast and stable set temperature. The circulation system (domestic circulation or external circulation) ensures a high degree of uniformity of temperature within the work area.
Applications
Bioengineering, Pharmaceutical Research, Chemical Analysis, Physical Experiments, Measurement and Testing, Material Testing
Steps
1. Inject an appropriate amount of suitable medium into the Tank.
2. Connect the device power supply.
3. Set the required temperature and alarm parameters through the large LCD control panel.
4. Choose domestic circulation or external circulation mode as needed.
5. Start the device and the system will automatically run and reach the set temperature.
6. After use, turn off the equipment and cut off the power according to the procedures.
Notice
• Please use the medium that meets the requirements and ensure that the liquid level is within a safe range.
Equipment should be placed on a well-ventilated and stable countertop.
• During operation, do not block the heat dissipation trend.
• Pay attention to the power requirements marked on the equipment and ground correctly.
Before performing maintenance or cleaning, be sure to cut off the power supply.
• If there is an abnormal situation such as over-temperature alarm, please find out the cause and troubleshoot before using it.
