Rapid temperature and humidity alternating test chamber

Product Introduction:

The rapid temperature and humidity alternating test machine is a device designed to meet the requirements of environmental simulation testing, widely used in electronics, automobiles, new energy, materials, etc.

The equipment has the functions of rapid temperature change and temperature humidity alternation, which can achieve a wide temperature range of -60 ℃~150 ℃ and a humidity range of 20%~98% RH. It can simulate the use scenarios of products in complex environments such as day night alternation and high and low temperature cycling.

It adopts a temperature and humidity control system and a multi-point sensor layout, with temperature uniformity of ≤± 2 ℃ and humidity uniformity of ≤± 3% RH, ensuring the accuracy of test data. It is equipped with an inner tank, refrigeration unit, and energy-saving heating module.

The device supports programmable multi-stage testing programs, can preset up to curve processes, is equipped with a touch interface and data storage function, and is easy to operate.

Characteristics of rapid temperature and humidity alternating test chamber:

Control method and features: Balanced temperature control system, controlled by PID method, ensures that the heating and humidification capacity of the system is equal to the moisture and heat loss, thus enabling long-term stable use.

1. The experimental system has a reasonable structural design, standardized manufacturing process, and a beautiful and elegant appearance.

2. The main functional components of this test box are equipped with good configurations, low operating noise, and good energy-saving effects.

3. The matching and assembly of components are good, and the main functional components are all made of good components, which improves the safety and reliability of the product and ensures the long-term and high-frequency use requirements of users.

Control system:

Touch panel, face-to-face input data, temperature and humidity can be programmed simultaneously, curve display, set value/display value curve.

Multiple alarms can be displayed separately, and faults can be displayed on the screen when they occur, eliminating faults and misoperations.

Multiple sets of PID control functions, monitoring functions, and displayed in the form of data on the screen.
