RGTB-525i™ is a practical, high-value tipping bucket rain gauge with a 6 inch (15 cm) orifice. RTBT-525U™ is the 8 inch (20 cm) variant. These two rain gauges are made in the US by Texas Electronics and balance performance with compact size and ruggedness. Dyacon adds it’s own versatile mounting bracket that can be used for mounting the rain gauges directly to any pipe, post, or flat surface, including directly onto the Dyacon tripod.

Like other tipping bucket rain gauges, RGTB-525’s use a high-reliability reed switch, that closes momentarily with each tip.
