Technical advantages
HW5500 adopts
High strength sheet metal casing, German KNF imported motor, Japanese Omron relay module, and Panasonic imported compressor.
Due to its high-precision sensors, microcomputer digital processing technology, enclosed enclosure space, and high seismic structural design, the system fundamentally improves the reliability and maintainability of the instrument.
Temperature and humidity control instrument: The screen operation is simple, and the heating power can be adjusted separately, the compressor delay start can be set, and the service life of the compressor can be protected.
Different sample holders can be placed for weighing different types of samples.Adopting a dual cold and hot air duct design, it can automatically switch between cold air ducts for more precise temperature and humidity control.
The observation window is made of customized materials, which have the advantages of transparency, insulation, and are not prone to steam frosting.The working area of the instrument is designed for separate operation, effectively avoiding the impact of refrigeration system vibration on the balance.
The heating and cooling system is independent.Humidification system: External isolation system, all stainless steel shallow surface humidification.
● Supply air circulation system: temperature resistant and low-noise fan, effectively removing static electricity from the sample
