Collecting rainwater at a water intake with a catchment area of 400 cm².
■ Connects to various data acquisition systems through diverse output interfaces ・ RS485 Modbus or proprietary ASCII protocol output ・ SDI-12 output ・ Voltage-free pulse contact output ■ Measured rainfall is regularly stored in non-volatile memory, and this information is retained even in the event of a power loss ■ Equipped with sophisticated functional features that reduce the influence of wind, ensuring better accuracy and stability in measurements ■ Built-in NTC temperature sensor to manage the internal temperature of the rain gauge ■ A heater-equipped version is available, which automatically operates under certain conditions to prevent snow and ice. No antifreeze or oil is required ▲ RS485 Modbus/SDI-12 output, voltage-free pulse contact (NO) output ▲ Heater included (HD2016R) operating temperature -20 to +70℃ (<4℃ start) ▲ Automatic drainage function, rainfall preservation function during drainage, wind influence reduction function ▲ Bird deterrent spikes φ3mm×H60mm×8 pieces, elevated mounting (optional)
