Hi guy just to let you guys know about a recall from apogge. Iam one of the case
Apogee Instruments is committed to helping you make accurate measurements. We recently determined that an op-amp in our radiation meters manufactured between December 1, 2008 and December 1, 2009 had an insufficient settling time. This caused our quantum, pyranometer, and UV meters to read high in high light levels. The meters are accurate from zero to 300 ìmol m-2 s-1, but are 5% high at 750 and 9% high at 2100 ìmol m-2 s-1. The affected serial numbers for your quantum meters, MQ-200, are 1001 to 1254.
