Transparent conditioning duct (200mm x 200 mm) for complete visibility of the process
Computer controlled via USB interface, with complete educational software including data logging, graph plotting with real time updates, mimic diagrams, data export
Educational software, replicating the psychrometric chart calculations
Six sets of Temperature and Relative Humidity measurements at the various stages of the process
RH sensors come with calibration values which can be entered into the software for best accuracy
Electronic flowmeters (2) measure the flow in each duct
Measurement of refrigerant pressures, temperatures and flow
Dual control of boiler setting with a fast heat up setting and a gentle setting for control
Transparent Duct for full visibility of the process and the components
Includes pre-heaters, humidifier, chiller/dehumidifier and reheaters
Fully instrumented, with temperature and Relative Humidity sensors at every stage of the process, plus an air flow sensor.
RH sensors calibrated for maximum accuracy.
