Regularly checking both values matters, but using separate meters makes routine monitoring less convenient. The Hanna HI98131 GroLine Combo Tester gives growers pH, EC, TDS and temperature in one waterproof pocket tester.\u003c\/p\u003e\n\u003cp\u003eWe recommend it for nutrient solutions with conductivity up to 6.00 mS\/cm. You can measure TDS using either a 0.5 or 0.7 conversion factor, while automatic temperature compensation adjusts readings as solution temperature changes. Hanna Quick Cal solution can calibrate pH and EC together, helping simplify regular maintenance. A graphite EC probe handles nutrient salts well, and the replaceable HI73127 pH electrode extends tester life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrowing Tip\u003c\/strong\u003e: Let the nutrient solution circulate before testing so the sample represents the full reservoir.
