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).

User-replaceable sensors (pH and ORP sensors) and cables and convenient calibration routine feature makes it extremely user friendly. Mil-spec (military spec) connectors, IP67 waterproof and rubber over molded case, and 1-meter drop tests ensure the instrument remains in your hands to provide years of sampling even in the harshest field conditions. The feature set of the Pro1030 results in a low total cost of ownership over the life of the product and proves that it is smarter, tougher, and more versatile.

YSI now offers an Extended Warranty for the Pro1030 (new instruments only).

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.
