    • Wide pH Range: measure pH from 0.00 to 14.00 pH
    • Selectable EC to TDS/ppm conversion factor: choice of either a 0.5 or 0.7 conversion factor
    • Automatic Temperature Compensation: all readings are compensated for variations in temperature, the temperature displayed in °C or °F along with pH, EC, or TDS reading
    • Large LCD with plant-friendly green backlighting: LCD can display all three essential hydroponic nutrient measurements at one time, a 3-second cycle of single measurements, or a real-time graph screen with options for measurement selection and log recall
    • Data logging for 30 days: logs every 15 minutes for the last 30 days, stores min, max, and average values
