Model GL820 and GL800 midi Data Logger Comparison

Beginning July 1, 2010 the GL820 midi Data Logger will replace model GL800. DATAQ Instruments has very successfully sold the GL800 over several years, and we thought that a comparison between the new and old models would be beneficial to our large installed base of GL800 customers. The primary takeaway is that the GL820 offers only performance advantages when compared to the model GL800 that it replaces. Those advantages are highlighted in the chart that follows. As always, please contact us with any questions.
