There are many important considerations when selecting and using a formaldehyde/VOC environmental test chamber. How many of these are you aware of? Today, we’ll share a few key points—have you noticed them?

Observation Area Required
To monitor test progress conveniently, the chamber should have an observation window.

Size Requirements for the Chamber
Is bigger always better? Considering budget and practicality, the chamber should meet testing needs without unnecessary excess. The internal dimensions should follow standard requirements (e.g., a 1m3 climate chamber for sample testing).

Consistency in Test Results
Under identical conditions (environment and samples), repeated tests should yield highly consistent and repeatable results.

Humidity Control Standards
Most chambers use the wet-and-dry bulb method for humidity control. To ensure precision, the chamber must maintain stable temperature control. According to industry standards (e.g., LYT 1612-2004), humidity should be controlled within ±2% relative humidity.

Air Exchange Rate Requirements
The air exchange rate refers to the introduction of clean external air into the chamber. This rate must comply with regulatory standards.

Ensuring Chamber Sealing Integrity
Since formaldehyde testing is highly sensitive, proper sealing is crucial to maintain accuracy and prevent leaks. Regular checks and prompt repairs are necessary if leaks are detected.
