EcoSense® EC300M Conductivity/Temperature

Accurate, economical, handheld instrument

The YSI EcoSense® instruments provide accurate data in the
most affordable package. The "M" stands for memory and the
instruments feature a real-time clock, larger memory and simple
data transfer to a PC with a built-in USB port.

The EC300M is easy-to-use, field-ready and utilizes a stable,
4 nickel electrode sensor design that results in accurate
measurements.

The EC300M measures conductivity, specific conductance,
salinity, TDS (Total Dissolved Solids) and temperature with the
following features:

• Rugged, waterproof, field-worthy case. IP-67 rated.

• Durable field probe and cables made in the USA. 1-,4- and
10-meter field cables available.

• Waterproof micro-USB port for transferring data to PC; no
software required.

• Holds 250 data sets; no need to write down data.

• Real-time clock for date/time stamp of saved data.

• User-selectable re-calibration prompt provides reminder to
calibrate.

• Automatic temperature compensation.

• Stable, four-electrode design provides accurate field
measurements.

• 1-year warranty on instrument and probe/cable assembly.

The EC300M is designed for quick, accurate results in an
economical platform. Easy-to-use, waterproof and backed
by a 1-year warranty, the EC300M is ideal for a wide-range of
applications.
