Programmable constant temperature and humidity testing machinePerformance parameters of
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 ℃~+150 ℃
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 high and low temperatures at the center point)
6. Temperature error: ≤± 1 ℃ (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 high and low temperatures measured in each test)
8. Heating rate: adjustable at 3 ℃/min (non-linear no-load)
9. Cooling rate: 1 ℃/min adjustable (non-linear no-load)
10. Humidity range (only for humid heat type): (20-98)% RH (refer to the temperature and humidity controllable range diagram, no active humidity or thermal load) Programmable constant temperature and humidity test chamber temperature and humidity controllable range diagram
11. Relative humidity error (wet heat type only): ± 2.0% RH
12. Work noise: A-level ≤ 65dB (A) (measured in a soundproof room with low echo and ambient temperature of 25 ℃); Using A-weighting, test the average of 8 points; Each testing point is 1 meter horizontally away from the noise source and 1 meter above the ground in height
