EZ20 Temperature & Humidity Data Logger
PRINT E-MAIL BOOKMARK  

The EZ20 is a compact data logger with a built-in temperature and relative humidity sensor. The logger is provided with two extra channels that can accept one external temperature/RH probe or external thermistor probe. The internal plug–in RH sensor is field replaceable. An internal Lithium battery, that lasts for up to 10 years, eliminates the chance of data loss due to dead batteries.

The logger can either be used as a standalone device or connected to a new or existing network so as to be a part of a real time monitoring system.

Multiple software options are available including TrendzLog software that meets 21CFR Part11 requirements
