We can offer operation video and English operation muanual. We can provide video-conference. If customers require on-site service, the transport and travel expense shall be borne by customer.
Features:
Rectangular complex layers of glass view window can be used for observation specimen when doing testing.
With anti-sweat heater unit of the window can prevent water vapor condensing water droplets, and high-brightness PL fluorescent lamp keeps box lighting.
Testing hole can connect external test power line and signal line and adjust specimen tray by up and down.
Airtight and closed double-isolated door can isolate effectively the internal temperature leakage.
Compressor circulation system is imported, it is more effective to remove condenser tube and capillary lubricants, and full ranges of series adopt environmental refrigerants (R-23, R-404).
Controller adopts imported 7 inches LCD touch screen, can display simultaneously testing values, setting values and time.
Controller has multi-stage program editing, temperature and humidity can make QUICK or SLOP control.
Built-in mobile pulley is convenient to move and display, and with a strong poisoning screw to fix position.
