Marathon's family of electronic data loggers have been designed to offer different models for varying applications. They range from the most exacting requirements such as laboratories who require NIST certification and calibration, to everyday use such as a temperature monitor for refrigeration of perishable products. All data loggers use an internal thermistor for measuring temperature and share the same basic palm-sized design or smaller design.
We offer a variety of Temperature Data Loggers to suit your needs.
Choose from the categories below:
Cryogenic Temperature Data Logging

microDL-200C: Liquid Nitrogen Datalogging
