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.
