Solutions for Excessive Temperature Fluctuations in High and Low Temperature Test Chambers

Source：LINPIN Time：2025-04-09 Category：Industry News

After putting a high and low temperature test chamber into operation, is it normal for the equipment to exhibit significant temperature fluctuations? This may indicate a malfunction, requiring prompt troubleshooting and resolution. Are there effective methods to address this issue?

Troubleshooting Steps:
Check the Relay

The relay component directly affects temperature stability.
Inspect whether the relay is functioning properly or if it is damaged.
If faulty, repair or replace it.
Inspect the Controller

Verify whether the issue stems from incorrect controller settings or corrupted data.
Ensure the controller itself is not malfunctioning.
If settings or data are incorrect, recalibrate immediately.
For hardware failures, consult professionals for repair or replacement.

Examine the Compressor

The compressor also impacts temperature fluctuations.
Confirm whether it is operating normally.
If faulty, arrange for repairs.
Performance Standards for Test Chambers
High and low temperature test chambers are used to evaluate the performance and parameters of materials under extreme temperature variations. They are widely applied in industries such as:

Military & Aerospace
R&D Institutions
Universities
Electronics
Automotive
Aviation
Temperature uniformity requirements:

Must be within ±2.0°C.
High-temperature fluctuations should not exceed ±0.5°C.
Low-temperature fluctuations should not exceed ±1.0°C.
If you observe excessive temperature fluctuations, follow the troubleshooting methods above to identify and resolve the issue.
