Repeatability: pH: ±0.02 pH; mV: ±0.1 mV; Temperature: ±0.2 °C
Temperature Calibration: 1 or 2 point with zero and slope adjustments
Temperature Compensation: -5 to +105 °C for Nearnst equation (auto/manual);
0 to 60 °C for auto buffer recognition
Solution Temperature Correction: Corrected to 25 °C, 0.1 to -0.1 pH units/ °C slope
Operating Temperature: -10 to 60 °C
