State-of-the-art, heavy-duty pH meters designed to provide laboratory results and accuracy under harsh industrial conditions.
These meters are provided with a series of new diagnostic features which add a new dimension to pH measurement by allowing the user to 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 (see instrument specifications).
- Custom calibration with up to five custom buffers (not for HI 98180/1).
- Messages on the graphic LCD for an easy and accurate calibration.
- Diagnostic features to alert the user when the electrode needs cleaning.
- User selectable “Outside Calibration Range” warning.
- Monitoring of the electrode aging.
- User-selectable “calibration time out” to remind when a new calibration is necessary.
They also offer an extended temperature range from –20 to 120 ºC (–4 to 248 ºF), using interchangeable temperature probes or temperature sensor inside pH electrode. These instruments can also measure with ORP electrodes with the capability to measure mV with a resolution up to 0.1 mV.
- Relative mV measurements
- Log on demand up to 300 samples (100 samples on each range - pH, mV, ISE)
- Auto Hold feature, to freeze first stable reading on the LCD
- GLP feature, to view last calibration data for pH, Rel mV or ISE
- PC interface
