Before purchasing a constant temperature and humidity chamber, you should fully understand some of its important performance indicators. Such as temperature range, temperature uniformity, temperature fluctuation, temperature change rate, temperature deviation, etc. These performance indicators are the basis for judging the equipment. This chapter is a small series for you to introduce these performance indicators in detail, I hope to help you choose:
1, temperature range
The temperature range is the extreme temperature that the studio can withstand and can reach. There is usually a concept that can control constant, and it should be that the extreme value can be stably operated for a relatively long time. Typical temperature ranges include extreme high temperatures and extreme low temperatures.
2, temperature uniformity
The temperature uniformity of the constant temperature and humidity chamber is also called the temperature and temperature uniformity. It is an important indicator for assessing the core technology of products. It refers to the maximum value of the difference between the average values ​​of any two points in the working space at any time interval after the temperature is stable.
3, temperature fluctuations
Temperature volatility is the control technology for this indicator. Refers to the difference between the highest and lowest temperatures at any point in the workspace at any given time interval after controlling the temperature to stabilize. There is a small difference here. "The workspace is not a studio. It is about an empty space in the studio that removes 110 from each side of the box wall.
4, temperature deviation
After the temperature is stable, the difference between the average value of the central temperature of the constant temperature and humidity chamber working space and the average temperature of other points in the working space at any time interval.
The above four points are important technical indicators for the purchaser to select the constant temperature and humidity chamber. Xiaobian here suggests that the purchaser can't be too hasty about equipment selection and hastily. You can consult a few more, compare more, choose the equipment that you like.
