How to choose the right temperature for high and low temperature alternating heat and humidity test chamber? High and low temperature test chamber This product is widely used in electronic electrician, automobile motorcycle, aerospace, rubber, plastic, metal,
Ship weapons, institutions of higher learning, scientific research units, etc. are one of the necessary test equipment for manual three-proof. The function of the high and low temperature test chamber is to test the performance of the test workpiece under high temperature and low temperature changes.
Due to the wide use of high and low temperature test chambers, and the unevenness of test equipment manufacturers on the market, users cannot correctly and effectively select suitable and high quality equipment when selecting test chambers. The following principles should be followed when selecting a high and low temperature test chamber:
First, choose the good HUMGINE brand high and low temperature test chamber as a high-precision test equipment. When selecting suppliers, in addition to considering technical problems, we must also consider the scale and brand of the manufacturer, so that from the source Ensure the quality of the high and low temperature test chamber. At present, there are more than 500 large and small manufacturers of high and low temperature test chambers in China, but the quality and level are uneven. Shanghai Huanzheng Test Equipment Factory is a responsible company, and its high and low temperature test chambers have independent knowledge. Property rights, core accessories are all imported famous brands,
And by the majority of customers unanimously recognized.
Second, choose the appropriate temperature range According to the relevant national test standards, often choose the temperature low temperature is -20 ° C or -70 ° C, but some scientific research units or military industry due to special requirements, you need to choose a lower -20 ° C, - 70 ° C, even deep cooling to -200 ° C, high temperature is generally 150 ° C, users can choose the appropriate temperature range according to their actual situation, manufacturers according to cost accounting, in general, the lower the temperature, the more expensive. Generally, the temperature range of the high and low temperature test chamber is -20 ° C ~ 150 ° C; -40 ° C ~ 150 ° C; -60 ° C ~ 150 ° C; - 70 ° C ~ 150 ° C;
-80 ° C ~ 150 ° C; -200 ° C ~ 150 ° C and other major types,
Third, choose the right volume:
The volume is selected based on the maximum workpiece volume of the test, which accounts for one-third of the volume of the high-low temperature test chamber, and cannot exceed two-thirds. The high and low temperature test chambers reserve 5CM for the front, back, left and right, and upper and lower sides of the studio during high and low temperature tests. To ensure that the circulation system of the test box can work normally, thus ensuring the temperature uniformity and fluctuation of the test box during operation. The volume of the high and low temperature test chamber is divided into 100L and 225L.
408L, 800L, 1000L, if the above volume can not meet the requirements, can be customized according to customer needs.
Fourth, choose a good after-sales service simply from the price comparison, it is impossible to buy a good product. Good after-sales service is very important to ensure the normal use of high and low temperature test chamber equipment. For the consideration of the after-sales service of the manufacturer, it is mainly to examine the scale and after-sales service capability of the manufacturer. One is to consider localized services, and the other is to consider the best price/performance ratio. Shanghai Huanzheng Test Equipment Factory has a professional after-sales service team and is equipped with after-sales service vehicles. It receives 15 minutes from the user for repair, and has 4 hours on-site service to ensure users can use the HUMGINE brand test equipment with confidence.
For example, Shanghai Huanjing Test Equipment Factory Co., Ltd., a comprehensive manufacturer engaged in the development, production, sales and technical services of medium and high-end mechanics and reliability test equipment and its edge products, has been able to control higher product quality and more for many years. Precision manufacturing skills, advanced management and management philosophy We aim to continuously develop new products and enhance the competitiveness of the market; and strive to reduce manufacturing costs, and return their profits to customers so that they can have high quality, reasonable price and service. The product in place.
