OW-34 tipping bucket rain gauge (Ohta Keiki Seisakusho) rental
We will convert the rainfall amount into a pulsed contact signal for rainfall observation. There are two types available: with and without Meteorological Agency certification.
***Features*** - The body is made of polycarbonate, and by incorporating a waist in the center, it reduces the impact of wind and improves the rain capture rate. - The tipping bucket rain gauge OW-34 for 0.5mm has obtained type certification from the Japan Meteorological Agency. - It allows for stable observation and measurement over a long period at a low cost.

Tipping Bucket Rain Gauge OW-34 (Ohta Keiki Seisakusho)
Applications/Examples of results
This is a tipping bucket rain gauge with a 200 mm water inlet, which has changed its body shape from the conventional cylindrical type to an hourglass-shaped cover, housing an inner container. The sensing part consists of a triangular bucket that tips over with the weight of 0.5 mm (standard) of precipitation, and a magnet attached to this tipping bucket closes a reed switch momentarily each time it tips, converting the rainfall into a pulsed contact signal for observation. There are two types available, depending on whether they are certified by the Japan Meteorological Agency.
