Portable pH/Ion Meter - Handheld ISE and pH Meter - -2.000 to 20.000 pH - IP67 Waterproof

The Master Science Portable pH/Ion Meter takes laboratory-grade pH and ion-selective electrode measurement into the field. It reads pH from -2.000 to 20.000 with ±0.002 pH accuracy, ion concentration from 1E-9 to 9.999E9, mV/ORP and temperature.

The hand-held body is IP67 waterproof, runs on a rechargeable lithium battery and is operated from a 4.3-inch colour touch screen. Up to eight calibration points are supported for pH and for ions, and more than ten ion methods are built in.
