1228Q44-Q46 are heavy-duty pH meters, designed to provide laboratory results and accuracy under harsh industrial conditions.
These instruments are provided with a series of diagnostic features which add a new dimension to the measurement of pH, by allowing the user to dramatically improve the reliability of the measurement:
- 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) for calibration
- pH calibration up to five calibration points
- Custom calibration by entering up to five custom buffers
- Messages on the LCD make the calibration easy and accurate
- Diagnostic features alert the user when the electrode needs cleaning
- Outside calibration range warning
- User-selectable “calibration time out” to remind when a new calibration is necessary
