KISTERS TB3 is a high-quality tipping bucket rain gauge for measuring rainfall and precipitation in urban and rural locations. Due to the integrated syphon, the gauge delivers high levels of accuracy across a broad range of rainfall intensities. With the optional heater the TB3 is the ideal device for cold climates.
By TB3’s tried and proven design long-term, accurate and repeatable results are provided. It is manufactured from high quality, durable materials providing long-term stability in the harshest of environments. It consists of a robust powder-coated aluminium enclosure, an aluminium base, and stainless steel finger filter and fasteners.
TB3 provides a finger filter that prevents the collector catch area from blocking when leaves, bird droppings and other debris find their way into the catch.
The TB3’s base incorporates two water outlets at the bottom allowing for water collection and data verification.
Maintenance of the TB3 is easy, because removal of the outer enclosure and access to the tipping bucket mechanism and finger filter assembly is made easy with quick release fasteners.
TB3 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 KISTERS 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.
