-The 7’’true color touch panel, smart operating system and high-performance processor contribute to easy and simple operation.
-Fuzzy PID control and programmed multi-section parameter setting.
-Precise timing function with week, day and hour modes.
-With the quick upgrade system, system program can be directly upgraded with USB.
-The system has automatic storage function and can store data of 3 years.
-Real-time check of temperature and humidity data or curve (for the last 8 to 10 hours).
-With event record function, 16,000 data can be recorded (including ON, OFF, menu parameter setting, fault alarm, etc.) and directly exported with USB.
-Imported Danfoss (SECOP) compressor and German EBM condenser fan.
-German HERAEUS temperature sensor and Austrian E+E capacitive transducer as the humidity sensor.
-Data monitoring standard access port (Ø50 mm) on the right, with silica gel plug.
-With CFC/HFC-free polyurethane foam as insulation material of the chamber, excellent thermal insulation and anti-condensation performance is realized.
-Samples can be observed through the inner glass door, thus avoiding affecting temperature and humidity due to door opening.-Flexible stainless steel -shelf system is easy to take out for cleaning and shelves have no sharp edges.
-Stainless steel liner (1.4301 / ASTM 304) and round corner design facilitate cleaning.
-Screensaver and coded lock prevent accidental operation.
-USB and RS485 interfaces.
-Chinese and English menu switch.
-When the temperature and humidity are set in the frostless range, the compressor works and the evaporator has no frost.
-When humidity is not needed, it can be set to zero and the equipment operates in the temperature mode; the control system can still ensure humidity inside the chamber.
-Energy saving: the energy saving effect is between 10% and 60% as the temperature and humidity settings change; water saving: the results change according to the temperature and humidity settings; for instance, a bottle of water can ensure operation of 30 to 60 days at the temperature of 25 °C and humidity of 60%. They jointly shorten working time of heating and humidification pipes, thereby extending their service life.
