Where to buy
The object
ATAGO's PAL-COFFEE (TDS) measures 0.00–22.00% TDS from a two-to-three-drop sample. Its stated resolution is 0.01%, stated accuracy is ±0.15%, and a typical measurement takes about three seconds.
Continuous measurement is intended to stabilize readings from recently brewed hot coffee. The IP65 water-resistant body can be rinsed as directed, though the prism still needs careful cleaning and a clear zero check between sessions.
