YSI Pro10 pH/ORP handheld water quality meter

YSI PRO Series 10 - Temp, pH or ORP Meter

The YSI Pro10 is a rugged, waterproof handheld meter that measures temperature alongside pH or ORP (redox). IP-67 waterproof and drop-tested, it's built for field spot-checks and compliance-related measurements.

Instrument only. Pair with a Pro Series 10 field cable (1, 4, 10, or 30 meter) — available with a built-in pH/ORP ISE/Temp sensor, or with a separate lab-grade pH or ORP electrode. Select your configuration below, or shop cables and sensors separately in the YSI Parts & Accessories collection.

  • Selectable pH or ORP Measurement: Supports either pH or ORP sensors, allowing users to tailor the instrument to their monitoring requirements
  • Integrated Temperature Measurement: Built-in temperature sensing supports accurate chemical readings across changing field conditions
  • Field-Hardened Construction: IP-67 rated waterproof housing and rugged connectors protect against water, dust, and rough handling
  • Interchangeable Cables & Sensors: User-replaceable probes and cable lengths provide flexibility for different sampling depths and environments
  • Straightforward Calibration Workflow: Simple calibration process designed for repeatable results and efficient field operation
  • Onboard Data Storage: Internal memory holds up to 50 data sets for later review and documentation
  • High-Visibility Display & Keypad: Backlit graphic screen and glow-in-the-dark keys improve usability in low-light and outdoor conditions
  • Long Field Runtime: Powered by C-cell batteries for extended operation without frequent battery changes
  • Multi-Language Interface: Supports multiple languages for use across global teams
  • Environmental Field Sampling: Spot-check pH or ORP and temperature in rivers, lakes, streams, and groundwater
  • Water & Wastewater Operations: Perform process checks and compliance-related measurements at treatment facilities
  • Industrial Water Systems: Monitor pH or redox conditions in process water, cooling systems, and discharge points
  • Regulatory & Compliance Monitoring: Support standardized water quality reporting with reliable, repeatable measurements
  • Aquaculture & Research Support: Track basic water chemistry parameters critical to aquatic system health
