Hanna GroChek pH Meter Runs off a simple transformer. The electrode sits in your water or nutrient tank and provides real time pH monitoring. The HI 1286 gel-filled pH electrode is interchangeable and the BNC connector is protected behind a waterproof sheath. The unique design of the electrode provides longer life in fertilizer solutions with high concentration of phosphate and nitrate. The pH GroChek is also supplied with a differential input and HI 1283 stainless steel probe to prevent potential grounding problems and thus ensuring longer life for your electrode.  You can set your own set point and be alerted of an abnormal situation with a flashing LED alarm. Measurements are highly accurate and the meter can be calibrated at one or two points. Unit runs without interruption on 12 VDC power supply.
