The Davis Instruments 7720 Rain Collector Heater is used in cold climates to measure freezing rain or the moisture content of snowfall (equivalent precipitation). Without the heater, frozen precip is not measured until it melts.

The Davis Weather 7720 requires access to AC power; may not be run using a solar power kit. Includes 24-watt, 24-volt heater with thermal cut-off switch, control unit, insulating reflective blanket, and AC-power adapter. Includes 50' cable.

Davis Extension Cable 7895

Shielded 4-conductor extension cables are available to extend the length of the 24-volt connection. Each includes a waterproof coupler kit for joining two cables together. Maximum total cable length is 120 feet. See the Accessories tab above to order.

5 stars Rain collector heater
Easily installed. Don't know how effective it is yet. The ambient temps have not been low enough to need it. In a month or two I will know the results.

4 stars Unprepared for hasty addition of heater.
I wasn't prepared for the exterior location I had to use to set-up the heater's transformer, but then I also hadn't anticipated the need, caused by the sudden arrival of a winter storm in October, to install it so soon.

4 stars Glad I bought it
With my first Vantage Pro2, I did not get the heater which, for all practicle purposes negates the value of having the rain collector. In Ohio, there are a significant number of days where the temp is below freezing and without the heater, your rain collection data is obviously corrupt. Extremely glad I have it, it's already well below freezing here and it is working like a charm. Easy to wire and install. The only reason I do not give it five stars is that the connection box is not weather proof so I had to buy a weather proof box to install the heater connection box in.
