What are the three big traps to be aware of when buying high and low temperature alternating damp heat test chambers
If it is said that drinking a glass of water can cause an accident, then in the jungle-like commodities, what else can not make people tremble? Safety is more important than Mount Tai. Who is to blame when something goes wrong? I can only blame myself. Generally, consumers like to look at the price of some products, but their perception of product quality is only at a shallow level. The following editor of Haotian will share with you the common misunderstandings in purchasing high and low temperature alternating damp heat test chambers. I hope everyone can draw attention.
Haotian high and low temperature alternating damp and heat test box and alternating damp and heat box constant temperature and humidity test box are similar products, but the name is different. Haotian high and low temperature alternating damp and heat test box is necessary for aviation, automobile, home appliances, scientific research and other fields Testing equipment is used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, alternating humidity and heat or constant temperature environment changes. Haotian reference standards are: GB/T2423.1-2008 test A low temperature test method, GB/T2423.2-2008 test B high temperature test method, GB/T2423.3-2006 test Ca constant humidity test method, GB/T2423. 4-2008 Test Db Alternating Damp Heat Test Method
1. Just look at the price and ignore the quality
Some consumers are blindly greedy for cheapness. Don’t you know that some manufacturers have to cut corners or even shoddy parts in order to enhance the competitiveness of their products. The actual level of life expectancy and other aspects is quite different from the level advertised in its advertisements. At first glance, buying this kind of test box seems to be a real benefit, but in fact it is tantamount to dragging a "short-lived ghost" who "eats" electricity home. On the contrary, wise consumers will not pay too much attention to the price of high and low temperature alternating damp and heat test chambers, and spend a few more money to choose a high-tech test chamber, and the maintenance cost saved in 7 or 8 years is considerable, which is quite Yu You "picked up" a high and low temperature alternating humidity and heat test box.
Second, it will not measure the advantages and disadvantages of the high and low temperature alternating damp heat test chamber from an overall perspective
Since the high and low temperature alternating damp and heat test chamber is an organic whole, the quality of Dongguan Haotian depends to a large extent on a weak function index, rather than a good one. Therefore, only the "all-round development" of the high-low temperature alternating damp heat test chamber with good overall quality can reflect its use value to the greatest extent. Therefore, to buy a test box that really suits you, you should comprehensively examine its performance from the aspects of cooling, heating, service life, and service.
Third, the wrong size
As we all know, Dongguan Haotian experiment high and low temperature alternating damp heat test box is the bigger the better, but Haotian also needs to consider whether the door and elevator size of the test room can pass smoothly. In addition, keep at least about 60 cm from the surrounding walls. To ensure air circulation.
Of course, there are many common senses of high and low temperature alternating damp heat test chambers that are easily overlooked by consumers. The author only reminds consumers of the above three main "misunderstandings".
So be familiar with the following points:
In terms of product performance, we also need to choose carefully! The key points need to consider several aspects!
1. Temperature range: What is the temperature range of the equipment? There are currently four standard temperature ranges for customers to choose from, A: 0℃~100℃; B: -20℃~150℃; C: -40℃~150℃; D: -60℃~150℃. If the customer requires non-standard temperature, it can also be produced, and the lowest temperature can be -90℃.
2. Circulation function: Whether the equipment has a temperature circulation function, that is: the temperature is repeatedly switched to the curve cycle. We call such equipment with cyclic function as high and low temperature alternating test chamber (GDJW). For the specific differences between the two, you can click to enter the technical literature of "Is the high and low temperature test chamber and the high and low temperature alternating test box a concept?"
3. Humidity range: Whether the equipment has humidity function. We call the high and low temperature damp heat test box or constant temperature and humidity test box with humidity range. The humidity range is generally controlled at 20%~98% RH (when the temperature is 25℃~80℃).
4. The choice of system control hardware. In terms of hardware purchase, it is mainly based on the actual operation of the customer, the test purpose and the combined product cost. For example, in terms of refrigeration, the general production adopts imported French "Taikang" fully enclosed refrigeration compressor units, American "Danfoss" thermal expansion valves, "Aigao" filter driers, Italian "Casto" solenoid valves and so on. In terms of control panels, there are domestically produced ordinary button type and South Korean imported large-scale full touch screen control methods. When making a specific plan, our company will send a product configuration list to the customer, and make appropriate changes according to the customer's requirements.
