Smaller loggers for versatile temperature monitoring

Under 1” 

Micropack III’s small size makes it easy to position your data logger very near or even inside monitored items. 


With no need for cords and wires, Micropack III allows even wider access and greater precision to monitor tight spaces. 


Use Micropack III for a wide range of applications from EtO pasteurization to sterilization to depyrogenation.
