Multiparameter Water Quality Meter
A portable or benchtop meter, often with a submersible sonde, that measures several water quality parameters at once, such as pH, conductivity, dissolved oxygen, temperature, turbidity and ORP.

Multiparameter meter calibration procedures
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
Design qualification (DQ)
Choose sensors, ranges, cable length, logging capacity and ruggedness for the planned field and lab work.
- 02
Installation qualification (IQ)
Record serial numbers of the meter and each sensor, install software and check the meter powers on and communicates with each sensor.
- 03
Operational qualification (OQ)
Calibrate each sensor and verify with independent standards (pH buffer, conductivity standard, DO saturation check) against stated accuracy.
- 04
Performance qualification (PQ)
Compare field readings with laboratory measurements on split samples and track calibration records over time.
Keep every Multiparameter meter in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
