YSI PRO Series 10 - Temp, pH or ORP Meter
The YSI Pro10 handheld meter was built for professionals who need dependable pH or ORP measurements without extra complexity. Designed for daily field use, it pairs pH or oxidation-reduction potential (ORP) with temperature in a compact, impact-resistant instrument that performs consistently in demanding outdoor and industrial environments. Its modular design allows users to configure the instrument for their specific monitoring needs, making it a practical solution for routine water quality assessments.
Note: This handheld cannot be used with combination sensors, NO3, NH4, or Cl sensors.
Choose your Meter and Cable below. If you select an ISE/Temp cable (rather than a lab-grade electrode), you'll also need a pH or ORP sensor — sold separately.
Compatible Sensors (for ISE/Temp cable variants only):
| Sensor | Part # | Price |
|---|---|---|
| 1001 pH Sensor | 605101 | $216.20 |
| 1002 ORP Sensor | 605102 | $258.52 |
