2. Patent

Constant Temperature humidity test chamber

ZL201620138459.2 A constant temperature humidity test chamber

3. Function

It simulates the products in the chamber where the climate condition of different temperature and humidity, such as high-low temperature operation and storage, temperature cycling, high-low temperature and high-low humidity, moisture condensation etc. to check its adaptability and changing performance.

It has different name like "climate test chamber", "environmental test chamber", "Damp heat test chamber" etc..

It's required to conforms to IEC, JIS, GB, MIL to reach the consistency (including test schedule, condition, method) under the international standard.

4. Sample application &

prohibited

The chamber applies to:

compatibility test for store, transportation and application of electric, electronic products, unit components, parts and other materials under high or low temperature / humidity;

The following samples are prohibited to be tested or stored:

- Inflammable , explosive and other volatile substances;

- Corrosive substance;

- Biont;

- Strong electromagnetic emission source.

5. Capacity & Performance

5.2. Temperature changing

rate

Heating rate: 2.0℃-4.0℃/min; Cooling rate: 0.7℃-1.0℃/min (average non-linear, no load)

5.3. Temperature fluctuation

±0.5℃

5.4. Temperature uniformity

±2.0℃

5.5. Temperature deviation

±2.0℃

5.6. Humidity & temperature

control range (refer to fig.)

20% ～98%R.H (purple part is controllable)

5.7. Humidity fluctuation

±2.5%R.H.

5.8. Humidity deviation

±3.0%

5.9. Humidity uniformity

±3.0% (≥75%); ±5.0% (＜75%)

※ The above temperature and humidity performance is measured under the condition of ambient temperature 25℃±3℃, relative humidity ≤85%, ,no-load and no sample inside chamber.
