Completely waterproof. The battery compartment is sealed against accidental splashing or brief submersion under one meter of water or plant food
It measures EC (conductivity), CF (conductivity factor) and PPM (parts per million) scales for high conductivity measurements for a wide range of crops
Quickly monitor your nutrient level to maximize your grow and ensure plants get the balanced feed they need; INCREASED measurement range compared to standard Bluelab truncheon
Measures (tds) EC, ppm 500, ppm 700 and CF with with automatic temperature adjustments; no calibration required (comes factory calibrated)
【Wide Uses】The salinity meter has a wide range of compatibility in daily life and strong practicability. Widely used in swimming pools, fisheries, drinking water, laboratories, etc. It is an ideal tool for household and industrial use
【Multi-function】Professional manufacturing, multi-function use, not only can detect the salt content, salt water pool and fish pond, but also can detect the salinity of sea water and salt water pool. Suitable for conventional aqueous solution. Salinity meter requires 4 Button Battery (Battery Not Include).
