bluelab Combo Meter, pH/EC-Meter, measuring range: 0.00-14.00 pH, 0-9.9 EC, 0-99 CF or 0-1990 ppm

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. Conductivity and temperature do not need to be calibrated as this is locked in during manufacture. - Measurement range: 0.00-14.00 pH, 0-9.9 EC, 0-99 CF or 0-1990 ppm 0-1990 ppm - Resolution: 0.1 pH/EC, 1 CF or 10 ppm - Accuracy: +/- 0,1 pH/EC, 1 CF or +/- 50 ppm - Operating environment: 0-45 °C - Four display options – EC, CF, ppm 500 and ppm 700 - Two display options for temperature (° C or °F) - No calibration required for conductivity or temperature - Simple two or three point push button calibration - Successful pH calibration indicators - Temperature at a push of a button - Simple push button pH calibration - Auto off function - Large easy to read display - Supplied with a quality replaceable bluelab pH Probe - Low battery indicator - 2 x AAA alkaline batteries included - Over and under range indicators
