The HI6000-2 module measures pH, ORP, specific ions and temperature.
Measurement
- Choice of Measurement Unit
- pH (HI6000-1, HI6000-2) – pH, mV
- ORP (HI6000-1, HI6000-2) – mV, Rel.mV
- ISE (HI6000-2 only) – ppt, ppm, ppb, g/L, mg/L, μg/L, mg/mL, μg/mL, M, mol/L, mmol/L, %w/v, user defined
- Reading modes:
- Direct and direct/autohold
- Known Addition, Known Subtraction, Analyte Addiiton,
- Analyte Subtration (HI6000-2)
Calibration
- pH calibration using
- Up to five Hanna Instruments pH buffers (pH 1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45)
- Up to five custom buffers
- mV calibration using a single point to calibrate offset.
- ISE calibration using up to five nominal standard values and/or up to five custom solutions (user supplied)
Recommended probes
For pH measurements, Hanna recommends the HI1131B double junction combination pH electrode, together with HI7662-TW temperature probe for use with these modules.
HI1131B is a glass body, double junction, refillable pH electrode with an indicating sensor made of high temperature (HT) glass. The double junction reference and HT glass design allow the electrode to be used in a
wide variety of applications.
Probe connection to the unit is secured through a galvanically isolated BNC connection.
HI7662-TW stainless steel temperature probe allows the meter to automatically temperature compensate (ATC) pH measurements.
