Technical Specifications:

1. Large-screen color touch screen with Chinese and English menu operation interface.

2. The standard test environment module and the moisture permeability test module are designed as separate units. The internal air velocity of the box does not affect the moisture permeability test module, and the temperature and humidity are more uniform.

3. The standard test environment module can be used independently as a constant temperature and humidity box.

4. Standard test environment module:

4.1. Temperature range and resolution: 15℃～50℃, ±0.1℃;

4.2. Humidity range and resolution: 30%RH～98%RH, ±1%RH;

4.3. Fluctuation/Uniformity: ≤±0.5℃/±2℃, ±2.5%RH/+2～3%RH;

4.4. Control system: LCD display touch-type temperature and humidity controller, single-point and programmable control;

4.5. Time setting: 0H1M～999H59M;

4.6. Sensors: Dry and wet bulb platinum resistance PT100;

4.7. Heating system: Nickel-chromium alloy electric heating heater;

4.8. Refrigeration system: Original imported French “Taikang” refrigeration unit;

4.9. Circulation system: Use a long shaft motor, equipped with a stainless steel multi-blade fan that can withstand high and low temperatures;

4.10. Inner box material: SUS # mirror stainless steel plate;

4.11. Insulation layer: Polyurethane hard foam + glass fiber cotton;

4.12. Door frame material: Double-layer high-temperature resistant silicone sealing strip;

4.13. Safety protection: Over-temperature, motor overheating, compressor overpressure, overload, overcurrent protection;

4.14. Heating and humidification shutdown, undervoltage and reverse phase;

4.15. Operating environment temperature: 5℃～+30℃ ≤85%R.H;

5. The standard test environment module meets the standard requirements. It returns to the specified temperature and humidity within 3 minutes after the box door is closed.

6. Refrigeration system: Original imported French “Taikang” refrigeration unit to ensure the long-term stable operation of the entire machine.

7. Moisture permeability test module is equipped with a dedicated air duct and a variable frequency control method to make the air speed, temperature and humidity more stable.

8. Moisture permeability test module is equipped with a high-precision air speed sensor to monitor the air speed in the test duct.

9. Two-layer cup holder design, standard with national standard moisture permeability cups.

10. Rotating sample holder, providing a more uniform test effect for samples.

11. Moisture permeability test module

11.1. Circulating air flow speed: 0.02m/s to 1.00m/s, driven by variable frequency, adjustable continuously;

11.2. Moisture permeability cup quantity: 16 (2 layers × 8 cups)

11.3. Rotating sample holder: (0 – 10) rpm (driven by variable frequency, adjustable continuously);

11.4. Time controller: Maximum 99.99 hours

12. Metal painted appearance, more exquisite and heavy.

13. Extra-large observation window, convenient for observing the test status of the sample at any time.

14. Power supply voltage: AC380V, 50Hz, 6.2KW

15. Dimensions (W × D × H): 900 × 1100 × 1800 (mm)
