Tipping Bucket Rain Gauge
Stainless steel tipping bucket rain gauge with 0.2 mm resolution.
Product overview
The BKC-Rain Tipping Bucket Rain Gauge is a reliable and economical rainfall monitoring instrument designed for accurate precipitation measurement in meteorological and hydrological applications. Using a precision tipping bucket mechanism and magnetic reed switch, it converts collected rainfall into electrical pulse signals for convenient data recording and analysis.
Designed with a debris-resistant collection funnel, insect-proof mesh, low-resistance tipping bucket, and built-in bubble level, the BKC-Rain ensures stable operation and dependable rainfall monitoring. It can be integrated with rainfall data loggers and monitoring systems to measure rainfall accumulation, intensity, and duration.
