TDSWand

The TDSWand replaces the EC Dipstick as the our flagship PPM meter. The lighted display is large and easy to read. There are no mistakes when the temperature compensating microchip quickly senses the electro-conductivity of the nutrient solution or water sample and automatically freezes the displayed reading. PPM, EC and CF scales are easily accessed by easy to read buttons. Cutting edge electronic circuitry keeps the meter in calibration for extended periods of time. The TDSWand is waterproof from the electrode up to the display, water resista
