Davis UV Sensor [6490]

This top - notch UV Sensor measures the sunburn - causing part of the UV spectrum. It enables you to show the UV index, dose rate, and both daily and accumulated doses. The multi - layer filter offers a spectral response similar to the Erythema Action Spectrum, while the diffuser provides an excellent cosine response. Its two - piece housing reduces radiation heating, allows the sensor to cool through convection, and keeps out water and dust. It comes with a built - in level and a 0.6 - meter cable. Compatible with both the original Vantage Pro and Vantage Pro2 (already included in Vantage Pro Plus and Vantage Pro2 Plus). You might also need a Solar Sensor (#6450) and a Sensor Mounting Shelf (#6673). Quick Guide (pdf) and Owner's Manual (pdf) are available.

Using this UV sensor is easy. First, install it in a proper location where it can be exposed to sunlight. The built - in level helps you ensure it's installed correctly. Once installed, connect the 0.6 - meter cable as per the instructions. It'll start measuring the UV spectrum right away, and you can view the UV index, dose rate, and doses on your compatible device. When it comes to maintenance, keep an eye on the two - piece housing. Make sure it's free from dust and water. You can gently clean it with a soft cloth if needed. Also, refer to the quick guide and owner's manual for any detailed troubleshooting. And remember, this sensor is compatible with Vantage Pro and Vantage Pro2, so use it with the right system for the best results.
