MR6662 Temperature/Humidity Card Loggers

The MR6662 small size and lightweight card logger is for simultaneous logging of temperature and humidity and are capable to store up to 6000 data (40days data at 10-minute measurement interval) of temperature and humidity. A large screen enables to display the data being stored at site. A software for data management through a personal computer is separately offered with a data readout unit. For humidity measurement, an interchangeable element of capacitance type high polymer film is used. The card logger conforms to CE.
