2. Testing method:

GB/T 5170.2-2008 Temperature Test Equipment

GB/T 5170.5-2008 Damp Heat Test Equipment

3. Temperature range: -70 ℃ to+180 ℃

4. Control accuracy: Temperature: ± 0.2 ℃, Humidity: ± 2.5%

5. Temperature fluctuation: ≤ 0.5 ℃

6. Temperature error: ≤± 1 ℃

7. Temperature uniformity: ≤ 2.0 ℃

Energy saving constant temperature and humidity test chamberController features:

(1) 7-inch large screen display, switching between Chinese and English,

(2) Control Algorithm: Adopting advanced expert PID control algorithm (9 sets of PID for temperature and humidity, 5 sets of PID for single temperature), supporting automatic parameter calculation.

Embedded dynamic tracking suppression overtravel algorithm.

Low temperature heating adopts a cold balance+heating automatic segmentation method, which can effectively reduce equipment power consumption.

High temperature refrigeration adopts intelligent adjustment method of electronic expansion valve, which can effectively reduce equipment power consumption.

(3) Fine control: supports testing of secondary protection.

When the temperature exceeds the user set warning line, an alarm can be triggered (without pause).

When the temperature exceeds the user set warning line, a pause can be triggered.

Automatic cleaning of waterways.

(4) Paperless Recorder: Built in paperless recorder function, can maintain uninterrupted test data for 10 years, supports multi file saving, and supports USB data export.

Supports multiple communication interfaces: RJ45 (wired Ethernet), RS232 (industrial MODBUS). Support multi unit network. Support computer monitoring.

(5) Testing method: Fixed value: can run with a slope and can stop at a fixed time.

Program: 120 programs/each program has 1200 independent segments, 9999 loops, and can link programs.

(6) If there is a power outage during the testing process, the following three power down restart modes are supported:

Stop testing/restart testing/continue testing before power outage
