With the continuous improvement of market demand and the continuous exploration of luxury brand positioning, a fast temperature change test box of middle and high-end brands can be purchased at a price of 300000 yuan; the continuous rise of domestic brands not only brings more choice space to consumers in terms of price, but today we will take a look at the domestic brands with imported equipment with high precision and long service life quality Test to see if the brand equipment has the same super cost performance as the market feedback.

1. 1.Temperature rise and fall rate: the reason why a fast temperature change test chamber is used to test the product performance is that there is a very high requirement for temperature rise and fall rate; the fast temperature rise and fall rate is first in line with the relevant technical standards, and second is to speed up the test efficiency and reduce the test duration.

2. Uniformity: not only to ensure the temperature rise and fall of the rapid temperature change test chamber, but also to ensure the temperature uniformity of each point in the chamber as low as possible. Generally, the standard error of the national standard for temperature uniformity and temperature gradient is ≤ 2 ℃. The minimum error we have seen so far is that the DUOHE test has achieved 0.3 ℃. The smaller the error, the more accurate the temperature range of the sample, and the test results will also be The more accurate.

3. Stable performance: the index of stable performance of rapid temperature change test chamber is not only accurate control, but also necessary for long-term and high load operation. Sometimes the test requires several months without shutdown, so the fast temperature change test chamber must be "hard core" in this respect.

Although it has excellent performance in hard core, DUOHE test is more user-friendly in terms of price positioning of rapid temperature change test box. For customers with high requirements in the middle and high-end market, DUOHE test is nothing more than a suitable choice.
