Description of hh-601b digital display temperature control low temperature circulating water tank
Low temperature water tank is widely used in petroleum, chemical industry, electronic instrument, physics, chemistry, bioengineering, medicine and health, life science, light industry food, physical property testing and chemical analysis departments, colleges and universities, enterprise quality inspection and production departments, to provide users with a hot and cold controlled, uniform and constant temperature field source for constant temperature of test samples or products It can also be used as heat or cold source for direct heating or cooling and auxiliary heating or cooling.
Low temperature tank structure:
The structure of low temperature circulating constant temperature water tank is metal rectangle, made of high quality cold rolled steel plate, 304 stainless steel tank, side digital display temperature controller, power supply and circulating pump switch.
Set temperature of low temperature tank:
Press set key to set or view the temperature set point. Press the set key once, and the nixie tube character starts to flash, indicating that the instrument enters the setting state. Press the △ key to increase the setting value, and press the ▽ key to decrease the setting value. If you press the △ key or ▽ key for a long time, the data will change rapidly. If you press the set key again, the instrument will return to the normal working state. After the temperature is set, the heating and circulating pump switches can be started. (if the temperature controller is intelligent, the temperature control manual shall be attached).
Usage of cryogenic tank:
Before use, please read the manual carefully and be familiar with the instrument and control panel. Use a megohmmeter to measure the power supply, plug and ground for poor insulation or short circuit. Set the experimental temperature according to the temperature setting method. After the temperature is constant, the experiment can be started. This constant temperature heating solution, the best use of distilled water, low temperature should use alcohol. It is forbidden to use river water and hard water. If tap water is used, the thermostatic bath should be cleaned once after each use to prevent the influence of scale accumulation on the heater on the constant temperature sensitivity
Product features:
1. The air-cooled fully enclosed compressor unit has high cooling speed.
2. The refrigeration system has multiple protection devices such as overheating and over-current. The circulating pump can lead the constant temperature liquid out of the tank to establish a second constant temperature field. It can also be used as a cold source to lead the refrigerated liquid in the tank to the experimental vessel outside the machine, which can be used for a long time.
3. The microcomputer intelligent control system is adopted. Touch the soft key to quickly set the temperature, easy to operate.
4. The deviation of temperature measurement is corrected by microcomputer, and the accuracy of digital display is 0.1 ℃.
