DESCRIPTION

OVERVIEW

The Davis 6490 UV Sensor measures the sun burning portion of the UV spectrum. Allows you to display UV index, dose rate, and daily and accumulated dose. Multi-layer filter provides a spectral response that closely matches the Erythema Action Spectrum. Diffuser provides excellent cosine response. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust. Requires Davis 6673 Sensor Mounting Shelf

*** Note: The Vantage Pro2 "Plus" models found on our main Davis Vantage Pro2 page include this component as well as the Davis 6450 Solar Radiation Sensor. If you're considering these components and haven't yet purchased your station, you can save money by purchasing the Plus model instead.

Great product. Pretty accurate!

Mounting device on the stand was tricky I would advise anyone installing this device to install on mount first and then mount on weather station after. I installed the mount and then the device on the mount while it was on the station. Was tricky to keep the plastic spring retainers on the bolts while on a ladder in 20mph winds. Works well when sun shines on it. As soon as sun goes behind house and it is in shade, UV drops to zero not sure if that is normal. I assume so.

Expensive, but useful

The UV sensor for Vantage Pro 2 was pretty easy to install (assuming you already have the sensor mounting shelf) and is straightforward to use. It's nice to be able to see if I'm going to be burned today, but I just wish it wasn't so expensive.

Great addition to my Vantage Pro

It was shipped immediately, and once it arrived I opened and inspected, then following the simple instructions installed it. Counting reading and installation was less than 1/2 hour. Now I know how long I can sit out on my deck without burning.
