Precise Level Measurement in a Compact Sonde

Measure level, flow, temperature and conductivity with the compact 600LS sonde. Rugged and waterproof, the YSI 600LS is perfect for tide gauge monitoring, wetlands level applications, ground water, estuaries, rivers, and more.

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

  • Overview

    The YSI 600LS is an economical logging system for long-term, in situ monitoring. It logs at programmable intervals and stores up to 150,000 readings. The 600LS has extreme level accuracy of +0.01 feet (0.003 m) from 0-10 foot depths and +0.06 feet (0.01 m) from 10-30 foot depths. Available with and without conductivity, YSI recommends conductivity when used in saline environments for the most accurate level measurements.

    Parameters available on the 600LS:

    • Shallow Vented Level (0-9 m, 0-30 ft)
    • Temperature
    • Conductivity

    Adding conductivity provides additional parameters including Resistivity, Salinity, Specific Conductance and Total Dissolved Solids (TDS).

    Features:

    • Fits down 2-inch wells
    • Easily connects to data collection platforms
    • Compatible with the YSI 650 MDS
    • Available batteries for unattended, internal logging applications
    • Compatible with the 650MDS​
