Beier’s stability test chamber accurately adjusts the temperature and humidity in the chamber through its control system to ensure that these parameters remain constant during the experiment. This control is usually achieved using advanced temperature control systems and humidity controllers, such as PID control technology and solid-state relays. At the same time, the stability test chamber is also equipped with equipment that simulates sunlight, such as the 2KW stability sunlight simulation lamp array test chamber, which can simulate various spectra of sunlight and provide constant light intensity, making the experimental results more accurate and reliable.

The stability chambers are commonly used for testing applications that include ICH guidelines, accelerated shelf-life studies, steady-state, stability, package testing, burn-in, curing, controlled temperature storage, and biomedical research among many others.

Standards
Stability test chamber adheres to standards: IEC61215, IEC61646, GB2423, ISO4892-2, IS4892-3.

Features

• Multiple models are available to meet diverse testing needs, from basic thermal cycling to accelerated stress testing.

• Some stability test chambers are designed to meet specific criteria with uniform light, temperature, and humidity distribution to meet testing requirements under different illumination conditions.

Construction

• The chamber’s lower part serving as a workspace and the upper part housing a computer-simulated array of light sources.

• The chamber top is equipped with a return air inlet for air cooling exchange, cooling the incoming air to ensure stable temperature control.

• The side walls are constructed with steady-state sunlight simulation full reflective panels, serving as secondary sealing and specialized for optical reflection control.

• Structural strength: the total weight-bearing capacity of the bottom plate inside the chamber is greater than or equal to 250 Kg (evenly distributed).

• The door opens singly, with the door hinges located on both sides of the chamber, and has a handle. It features a door-opening light-cutoff protection device and a maintenance functionality.

• The sample rack can secure photovoltaic samples of various sizes: 2000x1200x50mm, 1652x1000x50mm, 1494x1000x45mm, 1580x808x45mm.

• Testing lead holes: one side of the chamber is equipped with a lead hole with a diameter of 100mm, equipped with an insulated heat-insulating plug.
