TB7 Tipping Bucket Rain Gauge (0.2 mm)

The TB7 is a new generation high-quality tipping bucket rain gauge for measuring rainfall and precipitation in remote and unattended locations when used in conjunction with HyQuest Solutions Undercover data logger (see flip side) or a smart communication module.TB7 is a reliable low cost device with a very good accuracy across a broad range of rainfall intensities.The TB7s 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. Enclosure and base consists of robust UV-resistant ASA polymer, and fasteners and filter are made of stainless steel.TB7 provides a finger filter that ensures the collector catch area remains unblocked when leaves, bird droppings and other debris find their way into the catch.The TB7s base incorporates two water outlets at the bottom allowing for water collection and data verification.Features:– Type: non-syphoning- In-built bird guard- Individually buretted and batch calibrated- Long term stability- Minimal maintenance required- Robust design for all environments
