the cF Truncheon? It's easy to use, easy to read, extremely accurate...

measure nutrient strength for years, which is a lot more than can be
said for most of the competition! Fully waterproof and featuring an
automatic on/off function, the Bluelab cF truncheon has no external
switches or knobs and is fully factory calibrated so you will never
have to recalibrate it over time. We think every grower should invest
in a Bluelab truncheon as it really is worth it's weight in gold when
it comes to giving your plants the right strength nutrients.
