MicroLogger is a small Java logger that features full logging functionality and is really easy to add to existing projects. It was modelled after Log4J and the JDK

The trademarked name for our CR21, 21X and CR23X dataloggers. Our Microloggers traditionally are compact, self-contained (i.e., keyboard display, power supply are part of unit), and have a set number of I/O terminals (not card or module based like the CR7 or CR9000).
