Product introduction:

     The linear constant temperature and humidity test box means that during the work of the constant temperature and humidity test box, within a set period of time, its heating rate and cooling rate at any time point are unchanged.

     Compliance with standards: GB/T5170.5, GB/T10586, GB/T2423.1 Test A, GB/T2423.2 Test B, GB/T2423.3 Test Ca, GB/T2423.4.

Linear constant temperature and humidity chamber (also known as: rapid temperature change test chamber) provides high temperature, low temperature, high humidity, low humidity environment to compare the material changes and the degree of strong attenuation before and after testing of rubber, plastic, electronic products, etc. The machine can also simulate the container environment to detect the fading and shrinkage of rubber and plastic under high temperature and high humidity environment. This machine is specially designed to test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials.

Test temperature range:

G（-20℃~+150℃）

Z（-40℃~+150℃）

D (-70℃~ +150℃)

Studio size:

technical parameter:

Control Stability: Temperature ±0.5℃ Humidity ±2.0%

Distribution uniformity: temperature ±2.0℃ humidity ±3.0%

Heating rate: linear 3 ~ 20℃/min (optional)

Cooling rate: linear 1 ~ 20℃/min (optional)

Control System:

Control system: It adopts the LCD touch-type TEMI880 temperature controller imported from South Korea, and forms an electrical control system with electrical components such as Schneider from France, Fuji from Japan, and Shihlin from Taiwan.

product structure

Inner box material: SUS #304 mirror stainless steel plate

Outer box material: SUS #304 stainless steel plate or cold-rolled steel plate with paint

Insulation material: rigid Polyurethane foam + glass wool

Cooling System:

Refrigeration system and compressor: In order to ensure the cooling rate and minimum temperature requirements of the test chamber, the test chamber adopts a binary cascade water-cooled refrigeration system composed of a set of imported compressors.

The compressor adopts the fully hermetic "Taikang" compressor imported from France or the semi-hermetic "Bitzer" compressor imported from Germany.
