Preset Tropf Blumat

The Preset Tropf Blumat is a hand-calibrated sensor that takes the guesswork out of Blumat setup. No soil calibration required — just insert, set to your pressure range, and grow. Available in 5", 9", and Watering Head Only. Sensor Options ＋ 5" Preset Blumat — Best for small containers under 5 gallons, shallow-rooted plants, or capillary mat systems. 9" Preset Blumat — Best for larger pots and beds where you want to target root-zone moisture. Adjustable from surface level to 9" deep. Watering Head Only — Already have Blumat sensors? Swap just the head for the preset version. Includes a union for easy connection without replacing tubing. How Preset Calibration Works ＋ Each sensor is hand-marked in our Colorado warehouse with two color-coded reference points on the adjustment dial: Gold — for low-pressure systems like gravity setups Silver — for high-pressure systems like hose bibs or pump kits For medium-pressure systems, adjust between the two marks. The sensor is still fully adjustable at any time using the included adjustment key through the top access port.
