EcoSense EC300A Conductivity/Temperature

Accurate, economical, handheld measurements

The EcoSense® line of compact, handheld instruments provides the most accurate data in the most affordable format. The instruments feature an easy-to-use interface, one-hand operation, IP67 waterproof case, and low cost of ownership over the life of the product. The EC300A simultaneously measures conductivity, speciﬁc conductance, salinity, TDS (Total Dissolved Solids) and temperature with the following features:

Parameters:

Conductivity Speciﬁc Conductance Salinity Temperature TDS (total dissolved solids)

The EcoSense EC300A is also available as a kit with a 1-, 4- or 10-meter cable.

• IP67 Waterproof housing

• 1-year instrument warranty

• Rugged, weighted probe assembly

• Automatic temperature compensation

• 4- and 10-meter eld cables available

• Low battery indicator with 500 hour battery life

• Super-stable, four-electrode conductivity cell designed for the

eld

• Auto shutoff function after 30 minutes of inactivity

• 50 data set memory

The EC300A is designed for quick, accurate results in an economical platform. The ability to measure conductivity, salinity, TDS and temperature in a simple, compact handheld allows the instrument to be used across multiple application sampling strategies. With a one-year instrument and electrode warranty, waterproof case and ease-of-use, the EC300A will ﬁt your needs.
