WEATHER STATION Features: New Design for 2007. 300 ft* Wireless Range. Battery Operated. Meets NWS specifications. Lifetime guarantee on the collector. This gauge design eliminates the normal wire connection from the rain gauge to the indoor display. The battery operated transmitter operates up to 300 feet away. Just locate the gauge in an open area and read the rainfall amount on the indoor display. The 8" diameter collector meets NWS specifications for statistical accuracy. Every time the bucket tips, a count is transmitted to the indoor display and the gauge empties. You never have to empty the gauge. Each tip of the bucket shows one hundredth of an inch on the indoor display. The RAINEW WIRELESS rain gauge requires two "AA" batteries for the Transmitter, 3 "AA" cells and a alkaline button battery (included) for the LCD receiver/display. The electronics and enclosure were redesigned and improved for Spring 2007. The RAINEW collector has a lifetime guarantee. The transmitter, receiver, counters and switches are guaranteed for a year. Both recorders have a keyhole slot in the back for wall mounting.
