20L Steel Temperature Humidity Chamber promotion stability temp humidity chamber
Usage
This equipment is widely applied for electronic and electric products ,components and material by
constant high low temperature, temperature change ,cycling ,damp heat etc environment simulation
reliability test
Heating and humidifying system
1. Heater
Spiral nichrome tubular electric heating element heater , High accuracy temperature fluctuation and with long lifetime .
2. Humidifier
Use shallow slot method to humidify. Humidity measurment use wet and dry bulb method.
3. Secondary protection
3-1 Over-temperature protector:(protect the sample and the chamber)
3-2 Humidifier empty burn preventer(protect the humidifier)
