How to choose the right constant temperature and humidity test chamber
With the rapid development of science and technology, environmental test equipment has been integrated into various fields such as military industry, aerospace, schools, scientific research institutes, enterprises and institutions, etc., and the market's demand for the environmental testing industry is increasing. The constant temperature and humidity test chamber has become a must in test equipment An indispensable test instrument, then, the environmental testing industry is uneven. How can customers who have not used this equipment choose the appropriate constant temperature and humidity test chamber?
First of all: equipment size, temperature and humidity range, origin of various accessories, third-party qualification certification, manufacturer brand awareness
Equipment size: This item is considered according to the size of the customer's product and the number of placements. Of course, the size of the customer's use area and the elevator door, and the size of the laboratory door must be considered. If it is a small thing such as electronic parts, It is enough to choose a size of 45 * 45 * 50cm with a volume of 100 liters.If it is a large product such as a motor, you have to choose 800 liters or 1 cubic meter.If it is larger, you need to provide a size for the manufacturer to customize. Type constant temperature and humidity laboratory.
Temperature and humidity range: The humidity range of GB / T2423.2-2001 in the national standard is 30 ～ 98% RH, but since the current products are pursuing more accurate and accurate, some customers will mention 20 ～ 98% RH, of course , An experienced manufacturer can also do this, but it must correspond to a certain temperature point, because it is impossible to do humidity at 0 degrees, because 0 degrees are frozen, and it is impossible to do humidity at high temperatures of 150 degrees. It has been dried, which is a common sense. As for the temperature range, the high temperature is basically 130 ℃, 150 ℃, and the low temperature range is from 0 ℃, -20 ℃, -40 ℃, -60 ℃, -70 ℃, -80 ℃ is even lower, the lower the temperature, the greater the technical difficulty, and the higher the price. When choosing, you should choose the temperature and humidity point that you often do, rather than blindly pursue the lowest point, because you ca n’t use it, but At such a high price, this is not necessary.
Origin of various accessories: The cost of the equipment depends on the quality of the accessories, and the quality of the equipment depends on the quality of the accessories.Therefore, the life and quality assurance of the equipment and the price depend on the accessories. The low cost uses the accessories produced by some domestic small factories, which leads to continuous after-sales equipment and cannot be used normally. For example, the main components of Beijing Yashilin Company use imported "Schneider" and "Meilanrilan" components for better control. Temperature, digital display touch keys imported from Japan, PID microcomputer SSR temperature controller, the cooler uses the French original "Tai Kang" fully enclosed compressor. Refrigeration system adopts unit or binary low-temperature circuit system design, American "Eco" dry filter, Taiwan "Guanya" oil separator, Italy "Castor" solenoid valve, such internationally renowned accessories, the quality of the equipment is of course Get a strong guarantee.
Third-party qualification certification: It is whether the equipment can pass the third-party quality inspection of the equipment by the local or national quality inspection bureau or metrology institute.If there is a manufacturer's package ticketing equipment that can be certified by a third party, then you can rest assured of this equipment Bought.
The last one is the brand awareness of the manufacturer: This is very important. The brand awareness is a score from the customer base on the company's equipment quality. Beijing Yashilin Testing Equipment Co., Ltd. is located in Beijing, China. It is a professional environmental testing equipment and testing equipment. A high-tech enterprise integrating production, R & D and sales. The company already has a professional R & D center, a CNC punch press imported from Taiwan, and a CNC bending machine developed by China Aerospace. It adopts the most advanced automatic processing equipment such as electrostatic spray lines in China and an electrostatic debugging workshop that meets national standards. Ensure the quality appearance and performance of the product. http: // This is some classic customers who have cooperated, you can refer to it.
If you have a purchase intention for the constant temperature and humidity test chamber, but do not know how to choose it, then this article will give you great help. If you feel that the writing is good, you can also introduce your friends, colleagues and so on. At the same time, you can also put forward some of your views on the selection and communicate together.
