Its rugged waterproof housing is designed for humid growing environments, allowing growers and technicians to check nutrient strength and acidity with one portable instrument.\u003c\/p\u003e\n\u003cp\u003eThe pH range is 0.00 to 14.00, while conductivity extends to 6.00 mS\/cm. TDS can be displayed up to 3000 ppm using the 0.5 conversion factor or 3999 ppm using the 0.7 factor. Automatic temperature compensation helps maintain consistent results when nutrient temperature changes. The graphite conductivity probe is resistant to salt deposits, and the replaceable HI73127 pH electrode prevents disposal of the complete tester when the pH sensor becomes exhausted. Standard pH and EC calibration can be performed separately, or Hanna Quick Cal solution can calibrate both parameters through one simplified procedure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNutrient Testing Tip:\u003c\/strong\u003e Measure the mixed nutrient solution after circulation, then compare pH and EC with crop-stage targets before making corrections.
