How to Solve the Tricky Problems of High and Low Temperature Alternating Humidity and Heat Test Chambers

Source:LINPIN Time:2025-03-12 Category:Industry News

The high and low temperature alternating humidity and heat test chamber is a composite type of test chamber. The more functions it has, the more prone it is to problems. For example, when switching to a high-temperature test, the temperature change may not reach the expected value. In general, the air circulation system can be checked. For instance, if it takes a long time for the temperature to reach the target value, you need to check whether the damper is operating normally. If the temperature surges, then there is an issue with the controller, which should be addressed promptly, such as replacing the control instrument.
The device is prone to problems in the following areas: First, the duration for the temperature to decrease is long. This is generally because there is moisture in the working chamber. When conducting tests in a high and low temperature alternating humidity and heat test chamber, it is essential to ensure a dry environment. The number of test samples should not exceed the requirement, as this can prevent the air inside the working chamber from circulating properly. Second, when the temperature starts to decrease to a certain value and then begins to climb upward, with the temperature gradually increasing, this is generally because the external environment of the device does not meet the requirements, such as room temperature and humidity.
During the humidity and heat test, the test chamber may also encounter some problems. For example, a common issue in this test is that the actual humidity reaches the upper limit or the actual humidity differs significantly from the test requirements. When conducting humidity and heat tests, an important piece of equipment used in the high and low temperature alternating humidity and heat test chamber is the wet-bulb gauze. The wet gauze needs to be replaced in a timely manner; otherwise, prolonged use can affect the purity of the water. Due to the material, the gauze will harden after a period of use and will no longer be able to absorb moisture to maintain the dryness inside the working chamber. This is why the actual humidity may reach 100%. In addition to this, the humidification system is also prone to problems, such as a significant difference between the actual and target humidity levels. In this case, it is necessary to check whether there is sufficient water in the water supply tank of the humidification system and whether there are any abnormalities in the water level control. The above-mentioned problems are all minor issues that can be resolved through troubleshooting.
