I have purchased the dew master and the temperature sensor together. To test the units accuracy, I compared the unit statically to my weather station humidity meter. It was bang on . The Pegasus products are of excellent quality with good support. The Dew master is easy to use and operate. There are other comparable products on the market but with a higher price tag. The only item that could be improved would be a larger display. The unit arrived as usual from OT well packaged and on time . Steve at OT provides excellent service to the astronomical community Thank you.
