I purchased the VWR 4143 F (in part) as a comparative measuement to an EXTECH 445703 Hygrometer/Thermometer that I have been using for a few weeks. Both the internal and remote readings are very close, while the EXTECH is a degree higher. The callibration certificate that came with the VWR 4143 F, gives me greater confidence in its accuracy.
Also, my VWR 4143 F unit came with a smaller size digit display on the tenths of degree, so it is not all the same size numerals as pictured.
Pros: nice unit / nice price
Would recommend: Yes
