How to choose a walk-in constant temperature and humidity Test Chamber?

At present, walk-in constant temperature and humidity Test Chambers have been widely used in automobiles, mobile phones, electronics, medical, military and other industries. There are many kinds of constant temperature and humidity Test Chambers on the market. Due to its rapid development in CHINA's domestic market, many brands have been produced, but not all manufacturers can meet customers' needs in terms of price and quality. 

(1) use

The constant temperature and humidity Test Chamber is a commonly used equipment in reliability testing. It mainly simulates high temperature, low temperature and hot and humid environment to test the heat resistance, humidity resistance, drying resistance and low temperature resistance of the product. Therefore, it can do many test items about temperature and humidity:

1. Turn off the humidity function. The walk-in constant temperature and humidity Test Chamber is equivalent to a high-low Temperature Test Chamber. It has excellent technology and can perform high-low temperature tests, high-low temperature alternate tests, and constant temperature tests.

2. Turn on the humidity function of the main function of the entry room, and conduct a temperature and humidity test on the product, that is, a temperature and humidity cycle test.

2. Detection range

The constant temperature and humidity Test Chamber can test a variety of products, including electronic components, circuit boards, electrical appliances, plastics, coatings, coatings, building materials, hardware, LEDs, auto parts, etc.

For example, the electronic components on the car will use the walk-in compartment, which products are specific?

Relays, car horns, car signal flashers, car lights, various electrical switches, car wiring harnesses, car harness connectors, car fuses, car buzzers, car electronic alarms, car backup alarm distributors, spark plugs, distributors, Car cigarette lighters, car audio and video systems, speakers, etc.

3. Choose

Mainly depends on function and quality. Buying a car is often based on performance and looks. There are also two important indicators in the walk-in: product function and product quality. The function of the product usually depends on your needs, because the manufacturer not only has the regular model of the product, but also can customize the equipment with different temperature and humidity requirements, different box sizes, and whether it has a program test function.

The product quality of the constant temperature and humidity Test Chamber is reflected in the following three aspects:

1. The accuracy error and the uniformity of temperature and humidity inside the box, usually the manufacturer will provide these parameters, but what the buyer needs to do is to verify by himself or with the customer company close to you.

2. The failure rate of the equipment is low. For a constant temperature and humidity machine with stable quality, it is usually calculated on the basis of working 7 days a week and 24 hours a day, and it is normal to have a failure (except for human failure) every two years on average.

3. Long service life, the normal service life of a good constant temperature and Humidity Chamber is 10-15 years. The service life of the constant temperature and humidity Test Chamber depends on the material selection and sheet metal process. At present, there are two kinds of constant temperature and humidity testing machines on the market: iron plate painting machine and stainless steel constant temperature and humidity testing machine. In terms of service life, the service life of stainless steel is longer than that of iron plate painting. Of course, you can also ask the manufacturer to customize according to your requirements.
