Pro1030 pH or ORP, Conductivity, Salinity Instrument


Rugged and reliable, the YSI Pro1030 provides everything you need in a handheld instrument for the measurement of either pH or ORP along with temperature, conductivity, specific conductance, salinity and total dissolved solids (TDS).

The super-stable 4-electrode conductivity cell is built into the cable and will provide years of accurate data. The cells are designed for rugged field performance and are easily cleaned and require minimal maintenance.

Additional features include:

  • Smart calibration routine allows easy calibrations with the press of a button, remembers previous cal values and simply walks you through the calibration
  • Stores 50 data sets
  • Graphic, backlit display and glow in the dark keypad 
  • Available with 1, 4, 10, 20, or 30-meter cables (4-meter and longer cables include cable management kit)
  • View display with polarized sunglasses on
  • Multiple languages include English, Spanish, French and Portuguese
  • User replaceable pH or ORP sensors and cables
  • Conductivity cell built-in
  • 3-year instrument; 2-year cable warranty; 1-year pH and ORP sensor warranty
