Strategy analysis such as purchasing a cryostat
We often have such confusion when choosing a cryostat. There are so many brands and the parameters are similar. How to choose a good low temperature thermostat manufacturer?
First of all, we must understand the product characteristics of the cryostat and choose the temperature and accuracy that suits you best. No matter how good the product is, if it is not suitable for you, then buying it back is a waste of money and takes up space.
The thermostat requires precise temperature control of the temperature of the liquid in the tank (temperature control accuracy is 0.1 °C or even 0.01 °C ). The most commonly used method is heating with a resistance wire and cooling of the compressor, supplemented by a PID microcomputer self-tuning precise temperature control method to stabilize the temperature of the constant temperature bath at the required set temperature.
Second, look at the popularity of the manufacturers, market share. Just like buying a refrigerator and a TV set, a good brand of good quality must be more stable than the quality of a brand. At least won't buy back the total bad, the total repair. More of this part of the money, buy a peace of mind, a convenience. Factory direct sales, the country has after-sales outlets, buy back to rest assured.
Again, the bath is typically equipped with a highly stable platinum resistor PRT or other temperature sensor for temperature control and automatic protection of the bath, respectively. The controller uses a special noise suppression circuit to detect the small change in resistance required for a high-stability thermostat. The internal temperature of the instrument is measured using an AC bridge to reduce the thermoelectric potential. Custom, high precision, low temperature coefficient resistors ensure short-term and long-term stability of the temperature set point. Therefore, once the sensor fails, the thermostat is no different from the sink. Shanghai Zhixin uses the imported PT100 sensor to reject the fake and shoddy.
Finally, in terms of noise. Advanced filtering technology overcomes power supply noise interference and stray electromagnetic interference and radio interference. Proportional integral control is used to control the power supplied to the bath heater. Precision factory commissioning virtually eliminates the effects of overshoot, allowing the bath to quickly reach its maximum temperature stability after reaching the temperature set point. People will feel comfortable during the process of use. And it has anti-static protection function, which increases the safety of the whole machine. Even if the machine malfunctions, it is still people-oriented and safety-oriented.
The core technology is the key to the success of the cryostat, and the thermostat performance is superior to our thermal port technology. It has a cooling coil and a heater sandwiched on the side of the stainless steel cylinder of the thermostat. The bottom of the cylinder becomes a heat exchange port, and most of the heat enters and exits the bath through this port. The good insulation around the cylinder minimizes heat leakage. Good insulation to ensure a constant temperature.
