NEW!! The NOAH IV Precipitation Gauge

 (Approved National Atmospheric Deposition Program precipitation gauge)

ETI's NOAH IV is our newest all-weather precision precipitation gauge that weighs the entire contents of the internal collection container. Any precip that might adhere to the container walls is weighed and accounted for.

The NOAH IV can be configured with built-in infrared optics to ensure that the first drops of precip are measured. The optics also ensure that temperature and vibration excursions do not produce false precip indications.

The 8-inch diameter orifice has only a 1-inch vertical inlet, further reducing the surface area for precipitation to collect on.



Resolution 0.001 inch

Threshold 0.01 inch

Accuracy +/- 0.01 inch

Temperature Range -30 C to +50 C

Power Requirement +12 VDC (1 ma) without optics onset

Orifice (diameter) 8 inches

Capacity: 12 inches

Overall Height 30 inches


Windscreen - to reduce effects of wind on measurement. The windscreens are made of GE LEXANTM a space-age material resistant to weather and solar radiation.

Solar Power System - consisting of a 20-watt, 12-volt solar panel, regulator, and a 12-volt, 12-amp battery.
