Extech EC700 Waterproof pH Conductivity TDS Salinity Optical DO and Temp Meter

The Extech EC700 is a versatile, waterproof water quality meter designed for fast and accurate analysis across a wide range of environments, including aquaculture, laboratories, and water treatment facilities. This all-in-one instrument features interchangeable probes that measure pH, conductivity, TDS (total dissolved solids), salinity, dissolved oxygen (DO), and temperature, making it ideal for professionals who need reliable multi-parameter testing in the field or lab.

Built with a rugged IP67-rated housing, the EC700 is engineered to withstand harsh conditions. Its large LCD display shows multiple readings simultaneously, while automatic temperature, pressure, and salinity compensation ensures precise results. The included optical DO probe offers reduced maintenance, no oxygen consumption, and no minimum inflow requirements, enhancing usability and reliability.

The EC700 stores and recalls up to 99 readings, allowing users to track trends and changes over time. With a fast response time (under 30 seconds for DO), a compact design measuring 169 × 78 × 43 mm, and powered by 4 AAA batteries, this meter is both portable and practical for daily use.
