SED-50HWX-A Programmable Constant Temperature and Humidity Test Chamber. Provides constant or alternating high/low temperature and humidity test environments for heat, cold, dryness, and humidity resistance testing in el
Fonctionnement
Internal recirculating airflow: fan draws workspace air into a duct cavity at one end where heater, refrigerant evaporator, and humidifier/dehumidifier condition it; conditioned air blows back out, exchanges heat with the test specimen, and is re-drawn through the duct, cycling repeatedly to reach setpoint temperature and humidity. PID-controlled heater via AC contactor; Pt100 platinum RTDs for temperature; Pt100 wet/dry bulb for humidity; TEMI880 PLC touchscreen controller. Servo refrigerant flow control saves 30 percent or more energy.
