النشرة الإخبارية Extremely low temperature and constant temperature room

Extremely low temperature constant temperature room, also known as temperature and humidity cycle test machine, this equipment is Used to test the adaptability test for storage, transportation and use of electronic products, electrical products, photoelectric products, security products or other industrial products under the conditions of temperature and humidity cycle climate. The severity of the test depends on temperature, humidity, and exposure duration or cycle.

Use of equipment: Shenzhen constant temperature and humidity test chamber is mainly used for testing heat resistance, dry resistancet, cold resistance and moisture resistance of various materials used in the Shenzhen region. It is suitable for electronics, electrical appliances, food and vehicles, metals, chemicals, building materials, LEDs lamp, lithium battery, paint, power battery, shoes, clothing and other industries.

Technical parameters of the ultra-low temperature constant temperature room:

Temperature range: 0℃, -20℃, -40℃, -70℃～150℃.

Humidity range: 20%~98%RH (can be customized according to customer needs: low humidity type can reach 5%RH or more).

Heating rate: RT～150℃ for about 30min.

Cooling Speed: RT～0℃ about 20min RT～-20℃ about 40min RT～-40℃ about 60min RT～-70℃ about 100min

Temperature distribution uniformity: ±2℃ .

Temperature stability: ±0.5℃.

Moisture distribution uniformity: ±3%.

Humidity stability: ±2% RH .

The following criteria can be met:
