EZ90 Pulse data Logger
PRINT E-MAIL BOOKMARK  

The EZ90 data logger is a three channel data logger. An internal temperature sensor records ambient temperature and two channels designed for counting and recording digital pulse or switch contact closures.

These loggers can be used to trace number of times a switch opens and closes by maintaining a voltage potential across the input terminals on a continual basis. Each device is powered by an internal lithium battery that lasts for up to 10 years.

These loggers can be used as a stand-alone device or as a part of a network of loggers giving you access to real time data. The software allows the user to also display the data in custom engineering unit.
