pH meter PH-2011 ATC with calibration solution

pH meter PH-2011 is designed for measuring the value of "pH" in the range of 0.0 to 14.0 non-aggressive and non-flammable liquids, which must not be under electrical voltage. Use other than that specified above could damage this unit or cause injury. The device is designed for orientation measurements in the home. It is not intended for measurement, eg in areas where measurement with a calibrated instrument is required for legislative reasons.
