Model TB6 Tipping Bucket Rain Gauge

HyQuest Solutions’ TB6 is a non-syphoning high-quality tipping bucket rain gauge for measuring rainfall and precipitation in urban and rural locations. The TB6 is the device of choice for accurately measuring low rainfall events (0-50 mm/hr with better than +/-1 % accuracy),  because the water passes through the nozzle and enters the bucket directly allowing small rainfall events to be measured.

The TB6’s tried and proven design ensures long-term, accurate and repeatable results. It is manufactured from high quality, durable materials ensuring long term stability in the harshest of environments. It consists of a robust powder-coated aluminium enclosure, a UV-stable ASA  polymer base, and stainless steel fasteners and finger filter.


Easy maintenance

Removal of the outer enclosure and access to the tipping bucket mechanism and finger filter assembly is made easy with quick release fasteners. The finger filter can be removed easily during a field service. It ensures the collector catch area remains unblocked when leaves, bird droppings and other debris find their way into the catch. The TB6’s base incorporates two water
outlets at the bottom
allowing for water collection and data verification.


Output options

TB6 includes a dual output 24 V DC reed switch allowing for output redundancy or the addition of a second data logger. The second output could also be used for connecting HyQuest Solutions’
current meter counter CMCbt paired with the free FCD application that allow for easy and accurate field calibration even in noisy (urban) environments. The reed switch incorporates varistor protection against surges that may be induced on long, inappropriately shielded signal cables.
