| Manufacturer and type: | Hanna Instruments, HI9125 |
| Purpose: | Determination of pH of the solution |
| Kratki opis metode: | pH meter is an electronic instrument that consists of a measuring probe (glass electrode) and an electronic meter used to measure the pH (acidity or basicity) of the solution. The electronic meter is in fact a voltmeter that instead of volts displays the pH value as a measure of the activity of hydrogen ions around the round end of the glass electrode. |
| Tehničke značajke: | - pH Range: -2.00 to 16.00 pH - pH Resolution: 0.01 pH - pH Calibration: Automatic, one or two-point with five memorized buffer values (pH 4.01, 6.86, 7.01, 9.18, 10.01) - mV Range: ±699.9 mV; ±1999 mV - mV Resolution: 0.1 mV; 1 mV - mV Accuracy: ±0.2 mV; ±1 mV Temperature Range: -20.0 to 120.0 ºC, -4.0 to 248.0 °F - Temperature Resolution: 0.1 °C, 0.1 °F - Temperature Accuracy: ±0.4°C; ±0.8°F - Temperature Compensation: Manual or automatic from -20.0 to 120.0°C (-4.0 to 248.0°F) - pH Electrode: HI1230B PEI body pH electrode with BNC connector and 1 m (3.3’) cable (included) - Electrode/Probe: HI7662 stainless steel temperature probe with 1 m (3.3’) cable (included) - Input Impedance: 10¹² Ohms - Battery Type / Lifetime: 1.5V (3) AAA / approximately 200 hours of continuous use |
