Data Loggers

At its most basic, a data logger documents precise measurements at established intervals during a specified period of time. Different types of data loggers are made to document specific information like differential pressure, dissolved oxygen content, light intensity, plug load, relative humidity, rainfall temperature or voltage. Data loggers are generally compact, battery-powered units with an internal microprocessor, data storage, and sensors. Most can be used in a wide range of environments and record information for months at a time without human control. A data logger may be a stand-alone device or part of a larger instrument loaded with one or more external sensors.
