HOW IS THE PRO GAUGE SUPERIOR?

The revolutionary new ULTIMETER PRO Rain Gauge electronic rain gauge features superb accuracy and extraordinary reliability. Although it empties itself automatically it has absolutely no adjustments and no moving parts  the long term accuracy and reliability are molded in!

Operating on a drop-counting principle the PRO Rain Gauge senses every one-thousandth inch of rain and reports each one-hundredth inch back to the ULTIMETER Weather Station. In spite of its amazing resolution the PRO gauge can handle world record class rain rates of more than 10 inches per hour! The Pro Rain Gauge is 5 1/8 high and has a maximum diameter of 4 1/2. It can mount directly on a 1 pvc post (not included) or on an optional universal mounting bracket. The PRO Rain Gauge includes thermostatically controlled 18 watt heater a 110vac/24 vac power adapter with a 40 foot 2-conductor cable that makes power and signal connections to the junction box of an ULTIMETER 100 500 700 800 or 2000 Weather Station. We're sorry but the Pro Rain Gauge is not compatible with the ULTIMETER II because the II keyboard is not able to supply regulated voltage to operate the gauge.

HOW DOES THE PRO GAUGE WORK?

Accuracy of the PRO gauge starts with its exclusive parabolic funnel that traps wind driven rain so it won't splash out. Rain is funneled into a precision drop forming tube much like those you'd see in a hospital IV bottle. Each uniform drop coming out of the tube is equivalent to exactly 0.001 inches of rain. Each uniform drop falling from the tube is detected by four gold plated sensing electrodes that signal an electronic counting circuit. After each ten drops this circuit sends a signal to the ULTIMETER keyboard indicating that another hundredth inch of rain has fallen.
