Pro30 Conductivity Meter

The Pro30 is a handheld meter that measures salinity, conductivity, specific conductance, total dissolved solids, and temperature. Rugged, simple, and reliable. EPA approved for drinking water and wastewater compliance reporting.

Explore the Pro1030 handheld for measuring conductivity and pH, the Pro2030 handheld for measuring conductivity and dissolved oxygen, or the ProDSS (optical) or ProQuatro for a handheld that simultaneously measures multiple parameters. 

Instrument Only.  Cables, probes/sensors, and accessories sold separately.

• Overview

  The Pro30 is an economical, rugged, and versatile handheld conductivity meter.

  It is equipped with a super-stable 4-electrode conductivity cell built directly into the cable bulkhead, providing years of accurate data. The conductivity cells are designed for rugged field performance and are easily cleaned with a small conductivity brush. The electrodes require minimal maintenance.
