Ec/pH Sensor Arduino, Analog TDS Sensor Water Electrical Conductivity Sensor Arduino Price

3 in 1: EC and pH are vital measurements in Hydroponic systems. With the AEROSPRING 3-in-1 Multifunction Digital Meter you can accurately measure EC, pH and temperature values, accurate to +/- 2% EC, +/- 0.01 pH: and Temp: 0.9F. Comes with a lanyard. Automatic Calibration: Featuring three-point calibration, the meter can automatically identify calibration solutions of pH 4.00, pH 6.86 and pH 9.18. Included 3-pack pH buffer solution (4.00, 6.86 and 9.18). EC calibration solution not included. High Accuracy: Highly sensitive probe gives you a full measurement range of 0-19990μS/cm EC and 0-14 pH, Rsolution 0.01 pH; 1μS/cm; 0.1℃; 0.1°F; Multifunction Digital Meter green backlit display ensures you can read the measuring results under any lighting conditions. Important Hydroponic Measurements: EC measures the level of nutrients in your system and gives you a measurement of the quantity of available nutrients, allowing you to use this information to add nutrients to your desired level. Auto shut off: 5 Minutes.
