Is it better to buy a constant temperature and humidity test box or a high and low temperature test box Recently, a customer asked whether it is better to buy a high and low temperature test box or a constant temperature and humidity test box. In response to this problem, Dongguan Aisili Testing Instrument Co., Ltd. has given In contrast, I hope to help you. Dongguan Aisili Testing Instrument will explain to you the difference between the constant temperature and humidity test chamber and the high and low temperature test chamber: I learned a lot about the difference between the constant temperature and humidity test box and the high and low temperature test box in the daily customer consultation phone, and think that the constant temperature and humidity test box and the high and low temperature test box are equal, causing some unnecessary trouble! This article is about the difference between the two Aisi detection instruments in Dongguan, and I hope to help more new and old customers. There are roughly three types of temperature and humidity test environment test chambers: constant temperature and humidity test chambers, hot and cold shock test chambers, and high and low temperature test chambers. The constant temperature and humidity test box is also known as the high and low temperature test box, the high and low temperature alternating humidity and heat test box, the constant temperature and humidity test box, the programmable constant temperature and humidity test box, and the constant temperature and humidity test machine. The high and low temperature test box is also called high and low temperature box, high and low temperature alternating test box, high and low temperature cycle test box, low temperature and cold resistance test box. The cold and hot shock test box is also called high and low temperature impact test box, hot and cold shock test box, fast high and low temperature alternating test box. The laboratory is usually only used for high temperature and low temperature, but not for humidity, which is directly called the high and low temperature test chamber. To do high temperature and low temperature, at the same time to be able to do humidity, for circulation, it is called a constant temperature and humidity box. Of course, most manufacturers of constant temperature and humidity test chambers now refer to constant temperature and humidity chambers as high and low temperature chambers, so it can be said that they are called differently, but to be precise, high and low temperature chambers do not carry humidity. The other principles are the same, and the price is not much different. Most customers will ask for humidity for long-term consideration. Even if they do n’t now, they might use it in the future. For example, some customers bought a high and low temperature test box at the beginning. Half a year later, I suddenly wanted to do a humidity test. At this time, I had to buy a constant temperature and humidity box again, which wasted a lot of it. If the constant temperature and humidity box was considered when I bought it, the price would be lower than the high and low temperature test box It's only a few thousand pieces, and if you want to buy another one now, you need at least tens of thousands of pieces. Of course, some customers only need to do high and low temperature in order to consider the cost, or really do not need to do humidity, then buy a high and low temperature box. This can be based on company needs. In short, the appearance and shape of the constant temperature and humidity test box and the high and low temperature test box are basically the same, and the latter is missing a word "wet". From the literal meaning, it can be seen that the high and low temperature test box can not be tested for humidity test. The extra humidification system in the high and low temperature test chamber has all other functions. The details of the constant temperature and humidity test chamber are as follows: The constant temperature and humidity test chamber adopts Korean TIME880 type. 2. Fixed conditions can be set for time 0-999 H, touch KEY BOARD, can be set arbitrarily fixed or alternating conditions 3. With nine-point failure warning and simple maintenance method (TROUBLE SHOOTING) 4. Rising and cooling can be controlled by slope, and has the function of self-correcting temperature reference point. 5. The temperature sensor adopts DIN PT-100Ω (platinum sensor). 6. Temperature control adopts PID + SSR system synchronous coordinated control, which can improve The stability and life of control components and interfaces. (Japan Omron) 7. With PID automatic calculation function, it can reduce the inconvenience caused by manual setting. 8. In the setting or operation, if an error occurs, a warning signal will be provided. 9. The controller has the output of the recording signal terminal, which can be connected to the temperature recorder. (It is OPTION optional) (Japan OYO) 10. Remote monitoring and recording system can be connected (the test data can be directly displayed and printed on the computer through the host computer software). It is also important for ultra-low temperature performance experiments of electricians, electronics and other non-flammable and explosive materials. Constant temperature and humidity test chamber Humidification and dehumidification system: 1. Adopt electronic side-by-side micro-motion humidification system, with two magnetic reed switches, which can reduce the erroneous action caused by electronic type. 2. The humidification cylinder is made of stainless steel. 3. Adopt AC contact dehumidification method of evaporator coil dew point temperature (ADP). 4. With dual protection devices for overheating and overflow, it can be used with peace of mind. 5. The humidification and dehumidification system is completely independent. 6. The supply of humidifier water should be pure water or RO reverse osmosis water.
