Trident Meter is an all-in-one conductivity, pH and temperature meter. It comes with a one piece probe housing containing all 3 probes. The meter is dipped into the solution and the readings are displayed on two screens. As the Essentials Trident Meter is portable, it can be used any time and anywhere to help you manage your crops' daily nutrient requirements.
Calibration of the pH and EC/CF/ppm is very easy using the push buttons on the meter and calibration solutions.

Temperature does not need to be calibrated, as this is set during manufacture. The Essentials Trident Meter offers the added benefit of being able to select the display options for temperature as 'C or 'F and nutrient solution as CE, EC or ppm.
