MicroDataLogger® (MDL) Data Acquisition System

MDL UnitAEC developed and manufactured the MicroDataLogger® (MDL) portable data acquisition system in the late 1980s and 1990s when no other data logger like it existed: hand held, time series data collection, versatility in connecting to and powering third-party sensors, flash memory, ease of use ... the list goes on and on.  The driving need for the product was our energy engineering services and the need for short-term monitoring in facility operations evaluations, commissioning of new building systems, retro-commissioning of exisiting building systems, and desire to offer our own customers a completely integrated service offering.

AmbientThe MDL products manufactured by AEC have been out of production since early 2005.  The technology used to develop the MDL product was common in 1985, but parts are no longer available for repairs. The MDL products have proven quite durable, easy to use, and reliable to our customers; we expect that with proper use and care, they should continue to do so for our customers who still use them.  The primary concern for MDL users will be battery use and life for the data logger.  Information on maintaining and replacing batteries is found in User Support Materials, and information for obtaining new batteries is found under Product Support.
