KISTERS’ TB4 Series II is a high-quality tipping bucket rain gauge for measuring rainfall in urban and rural locations. Due to the integrated syphon, the gauge delivers high levels of accuracy across a broad range of rainfall intensities.

By TB4 Series II’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, a UV-resistant ASA polymer base, a teflon bucket, and stainless steel fasteners and finger filter.

TB4 Series II 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 base incorporates two water outlets at the bottom allowing for water collection and data verification.

Maintenance of the TB4 Series II 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. The new more spacious enclosure makes maintenance even easier.

Output options

TB4 Series II 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’ Bluetooth pulse 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.
