Measurement
- Measure pH/mV (pH) or mV/Rel.mV (ORP) with temperature
- Application-specific profiles allow quick and direct measurement without the need to update the sensor and system settings
- Active log during measurement
- Measurement stability indicator (using the Stability Criteria setting)
- Reading modes: direct and direct/autohold
- Temperature compensation can be Automatic (using temperature probe) or set manually
- Audible and/or alarm messages for measurements outside of predefined limits
- Galvanic isolation for pH/ORP measurement
Calibration
The HI6221 features 5-point pH calibration capacity with automatic recognition for standard buffers (Hanna and NIST buffers). In addition, a choice of standard or custom buffers for calibration along with non-volatile memory, which saves data and settings
