The YSI Pro1030 handheld multiparameter meter is a rugged and reliable instrument designed specifically for the toughest field work. Measuring pH or ORP plus conductivity and temperature (along with calculated values for salinity and TDS), the Pro1030 quickly provides highly accurate readings, even in the harshest field conditions.

The Pro1030 utilizes user-replaceable sensors and cables. An internal memory holds 50 data sets for later retrieval. The Smart Calibration feature makes it simple to make reliable measurements. 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. The mneter is protected by a three year warranty.

This meter requires regular calibration to perform at its optimal level. We strongly suggest purchasing calibration standards and solutions which are available as accessories.

Cable and probes are not included and must be purchased separately.
