Spot high and low temperature wet heat test chamberparameter performance

1. Test environmental conditions: The ambient temperature is+5~+28 ℃, the relative humidity is ≤ 85%, and there is no sample in the test chamber
2. Testing methods: GB/T 5170.2-2008 Temperature Test Equipment, GB/T 5170.5-2008 Damp Heat Test Equipment
3. Temperature range: 0 ℃/-20 ℃/-40 ℃/-70 ℃ -80 ℃~+150 ℃~200 ℃
4. Control accuracy:
a. Temperature: ± 0.2 ℃ (difference between controller set value and controller measured value)
b. Humidity: ± 2.5% (difference between controller set value and controller measured value)
5. Temperature fluctuation: ≤ 0.5 ℃ (temperature fluctuation is half of the difference between the measured temperature at the center point and the low temperature)
6. Temperature deviation: ≤± 2 ℃ (the average temperature displayed by the studio temperature controller minus the average temperature measured at the center point)
7. Temperature uniformity: ≤ 2.0 ℃ (temperature uniformity is the arithmetic mean of the difference between the measured temperature and the low temperature in each test)
8. Heating rate: 1-4 ℃/min adjustable (non-linear no-load)
9. Cooling rate: 0.7-2 ℃/min adjustable (non-linear no-load)
10. Humidity range (wet heat type only): (20-98)% RH (refer to the temperature and humidity controllable range diagram, no active humidity or heat)
