Time and time again ACR's Technology has proven itself to be the best for gathering real-world data. With trade-in programs that provide new data loggers when you trade in your older unit for a discount. ACR prides itself on producing the best product of its kind. Professionals expect to have tools that will meet the task at hand especially when faced with a survey or where the data is critical to keeping projects on time and on budget. It is imperative to choose a logger that will last the duration and provide all the information collected in a concise and efficient manner. ACR Proven Data Logging Solutions, including hardware and software, are the only products in the World that are up for the challenge.
Protection from Harsh Environments 
ACR Data Loggers are protected from the elements by covering the electronics with a specially formulated rubberized conformal coating. Since it is not known where a data logger may ultimately end up - exposed to pollutants, in the outdoors, or simply dropped from a ladder, every logger is made resilient to mechanical, environmental and chemical exposure. For instance, the plastics used have properties that protect not only the components inside, but also the information held within. Simple things can make a difference, such as having heat radiation colors compared to competitors' black body solar collectors - especially important when making thermal measurements, or use of standard-sized terminals that are pluggable so field wiring is simple.
Convenient User Interfaces 
ACR Software Solutions are proven to work on the latest Windows Operating Systems and Interface Cable drivers are registered with Microsoft for plug and play ease. Whether dealing with one logger or many, TrendReader software manages the connections, automatically displays a graph or tabular view accessing data files intuitively with a MS Office-like environment. Overlaying data from different Graph files is easy with the Graph List panel, which allows drag-drop functionality to build a tree of files and select individual lines to Plot on one page - no other provider has the same capability.
