Hanna Instruments HI-764103 DO digital probe with 4m cable (for use with HI-98199)
HI-764103 DO digital probe with 4m cable (for use with HI-98199)
When this electrode is used with the HI-98199 meter, measurements of dissolved oxygen, atmospheric pressure, and temperature can be achieved:
- Display units in % saturation or ppm (mg/L)
- Salinity compensation for saline waters – Manual entry of salinity values; readings compensated for salinity effects
- Built-in barometer – Automatic compensation for changes in atmospheric pressure; User selectable units
- Temperature compensation
- Automatic polarisation of probe at startup
- Ready-to-use HDPE pre-tensioned membrane caps are easy to replace
