Overview
TENLIN GDH-3015 High Accuracy Low Temperature Circulating Bath is a precision temperature control device with a Temperature range of -30 ° C to 100 ° C. It uses Air-Cooled fully enclosed Compressor refrigeration, and with the self-developed Control system and High Accuracy Sensor, it can provide a stable thermostatic environment with Temperature Fluctuations as low as +/- 0.005~ 0.02 ° C. It is suitable for various experiments and tests that require High Accuracy temperature control.
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-standard Pt100 Sensor, with imported electronic components, accurate temperature control.
3, with internal and external circulation system, 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 uniform and stable.
4, equipped with a complete protection system, including Compressor overheating, overcurrent protection, as well as over-temperature sound and light alarm and automatic load cutting function.
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. With High Accuracy Temperature Correction, resolution up to 0.001 ℃, Temperature Fluctuation up to +/- 005-0.01 ℃.
Principle
The Thermostatic bath reduces the temperature of the medium in the tank through a fully enclosed Compressor refrigeration system. The Control system monitors the temperature in the tank in real time through the High Accuracy Pt100 temperature sensor and feeds the data back to the microprocessor. The microprocessor uses the P.I.D algorithm to precisely adjust the output power of the refrigeration system according to the difference between the set temperature and the measured temperature, and circulates the liquid in the tank continuously through the domestic circulation pump, thereby ensuring the uniformity and Stability of the temperature in the working area. High Accuracy thermostatic control is realized.
Applications
Bioengineering, Pharmaceutical Research, Chemical Synthesis, Materials Testing, Measurement verification, Petrochemicals, Universities & colleges and research institutes and laboratories need High Accuracy thermostatic environment.
Steps
1. Place the device in a smooth and ventilated place and connect it to the power supply.
2. Inject an appropriate amount of heat transfer medium (such as silicone oil, water, etc.) into the tank, and the liquid level should exceed the heater and circulating pump in the tank.
3. Turn on the power switch, and the control panel display will light up.
4. Set the required temperature value through the buttons of the control panel.
5. Choose domestic circulation or external circulation mode as needed.
6. Press the run button, the equipment starts to work, and the cooling/heating system starts-up to reach and maintain the set temperature.
7. After use, press the stop button first, and then turn off the power switch.
Notice
Equipment should be placed in a well-ventilated environment away from heat sources and flammable and explosive materials.
• When using or replacing the heat conducting medium for the first time, ensure that the liquid level is appropriate to avoid dry burning or idling of the circulating pump.
• Set the upper and lower limits of the alarm temperature and ensure that the over-temperature alarm function is normal and effective.
• During the operation of the equipment, do not move or cover the entry and exit trends at will.
• Regularly clean the surface of the equipment and the heat dissipation filter to keep the ventilation smooth.
• If not used for a long time, please empty the liquid in the tank and keep the equipment drying.
• When a fault alarm occurs, the cause should be identified and ruled out before use. Non-professionals should not disassemble and repair by themselves.
