bluelab Combo Meter Each bluelab Combo Meter comes with two measurement probes included for testing conductivity, pH and temperature. It also allows you to select between display options for °C or °F and EC, CF, ppm 500 and ppm 700. As the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anytime and anywhere to help you manage your plants’ daily nutrient requirements. The pH level is calibrated using the calibration solutions included.
