Constant Temperature & Humidity Test Chamber: Sample Guidelines

Constant temperature and humidity testing is vital for environmental reliability. To ensure accurate results and equipment safety, Haida Instruments provides these essential guidelines for test samples:

1. Sample Shape & Safety
   • Liquids: Must be securely sealed to prevent leaks.
   • Flammable/Explosive Items: Strictly prohibited in standard chambers. Special modifications are required before testing.
   • Rubber Products: Place on a tray to prevent melting and sticking to racks during high-temperature tests.
   • Small Parts: Use solid trays to prevent them from falling through the standard perforated racks (approx. 5x5mm holes).
2. Sample Volume
   • The 1/3 Rule: Test samples should not exceed one-third of the chamber's internal volume. Overloading obstructs airflow, leading to uneven temperature and humidity distribution.
3. Sample Placement
   • Center Positioning: Place samples in the middle of the chamber.
   • Clearance: Do not block the top air ducts or place samples directly on the bottom. Adjust rack spacing based on sample size and quantity to ensure uniform exposure.

📌 Friendly Reminder from Haida Instruments: The accuracy of constant temperature and humidity test results depends not only on the equipment's performance but also on standardized user operations. Following these guidelines will not only ensure scientific test data but also effectively extend the service life of the equipment.
