Reliable rainfall data starts with a rain gauge that keeps working in exposed outdoor conditions. HD2015 measures precipitation with a calibrated tipping bucket and sends each tip as an impulse through a normally closed reed contact, ready for recording by a data logger or pulse counter.
Built for environmental monitoring, the instrument uses corrosion resistant materials, a 200 cm2 collector area and ingress protection (IP) 65 housing. The collector cone guides water into the bucket and has a non-stick coating for better flow, while a removable filter helps prevent leaves or debris from blocking the outlet.
For colder sites, heated versions support operation down to -20 °C and activate heating around +4 °C to help prevent snow deposits and ice formation. Model options cover 0.1, 0.2 or 0.5 mm/tip resolution, with maximum rainfall rates up to 600 mm/h or 1000 mm/h depending on the version.
The collector cone channels rainwater into a calibrated bucket. Once the set level is reached, the bucket tips, discharges the water and generates a pulse.
Measurement can be corrected using rainfall-rate correction curves when pulse timing is logged. With the HD2013-DB data logger, correction can be applied automatically.
Heated models operate with 12 Vdc or 24 Vdc power supply, depending on the version, and use a 75 W heating circuit.
The rain gauge is supplied for ground installation with three height-adjustable support feet. Raised installation on a mast is possible with the optional ACCR001 support.
A removable filter sits in the collector cone for periodic cleaning, and the cone surface is treated with a non-stick coating.
