4. Provide host computer operating software, support XP, Win7, Win8, Win10 systems
5. Heated observation window with LED interior lighting
6. Using French Taikang fully enclosed Compressor, A/B model is mechanical single-stage compression refrigeration, C model is cascade Compressor refrigeration
7. Equipped with multiple safety protection systems, including Compressor overpressure protection, humidification pipe dry burning protection, test space overtemperature protection, etc
Principle
The equipment adopts equilibrate temperature control mode combined with intelligent cooling capacity control and intelligent electrical control, and realizes temperature regulation through mechanical single-stage compression or cascade compression refrigeration system. Humidity control adopts wet-bulb temperature meter method, and heat exchange is carried out through high-efficiency slope evaporator and SWEP plate cold heat exchanger to ensure accurate and stable temperature and humidity.
Applications
Temperature test, humidity cabinet test, high temperature test, low temperature test, constant humidity cabinet test, alternating humidity cabinet test
Standards
GB/T5170.2-2008、GB/2423.1-2008、GB/2423.2-2008、GB/T5170.5-2008、GJB150.3、GJB150.4、GB2423.3-93、GB2423.4-93
Steps
Connect the power supply (220V/25A) and ensure the correct phase sequence
2. Set operating parameters through a 7-inch TFT color LCD display
3. Select the setting mode or the program mode (100 sets of programs can be preset)
4. Start the device running
5. Monitor and export data via PC software or Interface
Notice
• Equipment installation needs to ensure that the power phase sequence is correct and equipped with phase loss protection
• Check that the humidification system water supply is normal before use to avoid dry burning
• Regularly check the refrigeration system piping to ensure no leakage
• Pay attention to the over-temperature protection setting of the test space when operating
• Keep the equipment well ventilated to avoid blocking heat dissipation
• Use the provided USB port or Ethernet connection when exporting data
• Pay attention to the solenoid valve spool cooling protection during maintenance
