If the temperature exceeds the set value during testing in a constant temperature and humidity test chamber, how should we resolve it? Are there any emergency response measures?

As we all know, temperature overshoot in a constant temperature and humidity test chamber can affect the accuracy of test results. Therefore, such situations require prompt attention. Temperature overshoot refers to the temperature exceeding the allowable range. However, some degree of overshoot is permissible under certain conditions:

If the test point allows for a certain temperature range, the overshoot may vary within approximately 2°C.
If the temperature exceeds a specified stability limit, the overshoot should not exceed 2% of the test point.
For example, within 0–100°C, the overshoot should not exceed 2°C.
For temperatures above 100°C, the overshoot should not exceed 2% of the test point.
If the temperature overshoot falls within these ranges, it is considered acceptable. However, if the overshoot exceeds these limits, it is necessary to investigate whether a malfunction has occurred. In such cases, contact the manufacturer’s technical personnel for calibration or seek assistance from a professional service provider.

After purchasing the equipment, users should familiarize themselves with the product specifications of the constant temperature and humidity test chamber. This will help operators determine whether the issue is within controllable limits and take appropriate corrective measures. Our company not only provides high-quality testing equipment but also offers continuous after-sales support to promptly troubleshoot any issues.

Generally, the control system is the “brain” of a constant temperature and humidity test chamber, determining critical parameters such as heating rate and accuracy. Many modern devices use PID controllers. Our company’s constant temperature test equipment features an upgraded control system with high precision and advanced automation.

Currently, we offer a variety of chamber sizes to meet different testing requirements. Domestic and international customers can select the most suitable model based on their material characteristics. We welcome visits to our facility for on-site inspections and equipment purchases. Our company is committed to providing environmental testing solutions and high-performance equipment for the industry.
