Notes: 1. Nonstandard test chambers can be customized. 2. Above parameters are measured when the ambient temperature is +25℃ and circulating water temperature is +25℃, without sample. 3. The temperature fluctuation is tested in accordance with GB/T5170.2-2008 standard. For GB/T5170.2-1996 standard, the fluctuation is ±0.5℃. 4. The above-mentioned products are designed with a humidifier. 5. The entire test is conducted in accordance with GB/T7762-2003 standards.
