The AZ EC Stick Nutrient Meter tells you how strong your feed actually is: dip the end into your reservoir or bucket and a column of blue LEDs lights up against scales for EC, CF and ppm, on both the 500 and 700 scales. There are no buttons and nothing to calibrate, it corrects for water temperature from 0 to 50°C, and it's IP67 waterproof and floats if it slips into the tank. It reads nutrient strength only, not pH, and the LED scale moves in steps rather than showing a decimal readout, so it's built for fast, dependable checks rather than lab work.\u003c\/p\u003e\n\n\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; margin-bottom: 2rem;\"\u003e\n\u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n\u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eNothing to calibrate\u003c\/strong\u003e\u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eFactory calibrated, with no buttons, no calibration solutions and no menus.
