The RMS mini loggers are the perfect solution to monitor your cold storage applications. Using an ISM signal, the loggers can be placed anywhere you desire with no need to worry about cabling. The loggers are equipped with interchangeable NTC's that can cover a range from -200°C to +650°C. While refrigerators, freezers and extra-cold freezers are commonly used for the lower temperatures, cyropreservation may be required based upon the application. Measurements are then carried out at -80°C when using solid carbon dioxide or at -196°C using liquid nitrogen.
