The Orion 250Aplus is a multi-purpose, pH meter for one-handed field operation, featuring built-in electrode storage sleeve with cable management. Calibration is fast, easy and accurate using two-step autocalibration (built-in Auto-Buffer-Recognition of three buffers) and automatically calculated and displayed electrode slope value. The mV mode allows quick and easy ORP measurements. Meter provides choice of speed or accuracy with selectable resolution and simultaneous display of both pH and temperature. Features RS232 communication for connection to optional Orion 900A printer or computer. New ORP Mode allows standardization to the Standard or Normal Hydrogen Electrode used to define Oxidation Reduction Potential (ORP).
