Up to eight simultaneous measurements in one body, reducing wiring and deployment compared with separate instruments
Portable integrated multiparameter platform
MP301 Integrated Multiparameter Water Quality Analyzer
MP301 combines sensors, data acquisition, storage and Modbus RS485 in one pressure-rated probe body. The HDC-100A handheld supports field viewing, configuration, calibration and export. The final electrode set is confirmed for the real water and objective.

What to confirm before selecting the electrode set
Up to eight parameters describes platform capability; it does not mean every electrode is supplied as standard. Ion-selective electrodes also change the documented maximum depth. Water matrix, ranges, depth, calibration, interferences, power and communications must be reviewed before quotation.
- 01Confirm parameters, minimum/normal/maximum values and simultaneous channel count
- 02Confirm depth, pressure, temperature, velocity, fouling and cleaning conditions
- 03Confirm handheld, logger, Modbus, Bluetooth and supervisory interfaces
- 04Confirm cable, power, solar supply, mounting and field-maintenance method
