Temperature and humidity comprehensive test bench

1Temperature and humidity comprehensive test benchPurpose:

Mainly providing temperature and humidity changing environments for scientific research and production units in aerospace, aviation, petroleum, chemical, electronics, communication, etc. At the same time, electric vibration stress can be applied to the test sample in the test chamber according to the prescribed cycle for users toConduct comprehensive stress screening tests on the whole machine (or components), electrical appliances, instruments, materials, etc. for temperature, humidity, vibration, etc., in order to evaluate the test samplesEvaluate the adaptability or behavior of the test sample. Compared with the effect of a single factor, it can more accurately reflect the electrical and electronic productsThe adaptability of products to temperature, humidity, and vibration combined environmental changes during transportation and actual use, as well as the exposure of product defects, is an important testing method throughout the entire process of new product development, prototype testing, and product qualification testing.

IITemperature and humidity comprehensive test benchFeatures:

It has an extremely wide temperature and humidity control range, which can meet various needs of users. By adopting a balanced temperature and humidity control method, it can obtain a safe and accurate temperature and humidity environment. It has stable and balanced heating and humidification performance, and can achieve high precisionHigh temperature and humidity control. Equipped with high-precision intelligent temperature regulators, temperature and humidity are displayed on a color LCD touch screenThe screen can be used for various complex program settings, and the program settings adopt a dialogue mode, making the operation simple and fast. refrigeration circuitAutomatic selection, the self-control device has the performance of automatically selecting and operating the refrigeration circuit according to the set temperature value, achieving direct start of refrigeration and direct cooling under high temperature conditions.
