Control method and characteristics
High precision microcomputer temperature and humidity systems by PID controlling SSPR reduce the
system’s heating and humidification amount, to achieve low power consumption, energy saving, carbon
reduction effect. Intelligent electronic control of cooling, heating, humidity control, so it could be used long-
term stability.
Application
Applicable to environmental adaptability and reliability test in such industrial units as electronics, electrical
appliance, battery, plastics, food, paper product, vehicle, metal, chemistry, building material, research i
nstitution, inspection and quarantine bureau, university etc.
