Rainfall monitor with battery operated 900mhz transmitter No cables makes it easier than ever to bring the weather story into your home. This wireless version of our popular Rainwatch instrument operates at a powerful 900mhz which allows for up to 300' transmission distance between sensor and read-out in typical residential installations. When rain falls, Rainwatch receives updates every 2 seconds. The wireless transmitter is housed inside the collector bucket and operates for up to 18 months on 2 AA batteries (included). An attractive companion to any instrument (digital or analog), Rainwatch displays either long or short term rainfall with the flip of a switch. Select the length of time for each counter with the reset switch. Collect annual rainfall in one memory, and weekly or daily rainfall in the other. LED panel displays rainfall from .01" to 99.99" with an inch/cm conversion chart. A single 9V battery (not included) will collect and maintain data for up to 1 week in case of power failure. Outside rainfall collector meets NWS specifications for size and accuracy, and is self-emptying for your convenience. Includes 900mhz transmitter/rain collector, AC adaptor (for indicator) and installation hardware. A single 900mhz Wireless Receiver (sold separately) is required to operate this system.
