YSI® 650MDS Display and Logging System












Overview:

Log real-time data, calibrate YSI 6-Series sondes, set-up sondes for deployment, and upload water quality data to a PC with the feature-packed YSI 650MDS (Multiparameter Display System). Designed for reliable field use, this display and data logger features a waterproof IP-67, impact-resistant case.


Either sonde can easily connect to the YSI 650 handheld logger/display, YSI 6200 DAS (Data Acquisition System), web-enabled YSI EcoNet® or your own data collection platform, via SDI-12, for remote and real-time monitoring applications.


Battery Life

With the standard alkaline battery configuration of 4 C-cells, the YSI 650 will power itself and a YSI 6600 sonde continuously for approximately 30 hours. Or, choose the rechargeable 120 v battery pack (YSI Part # 6113) option with quick-charge feature.


Optional Barometer

Temperature-compensated barometer readings are displayed and can be used in dissolved oxygen calibration. Measurements can be logged to memory for tracking changes in barometric pressure.


Optional GPS Interface

Designed to NMEA protocol, the YSI 650MDS will display and log real-time GPS readings with a user-supplied GPS interfaced with YSI 6-series sondes.


Memory Options

Standard memory will allow for approximately 150 data sets. Exact logging capacity is dependent on the number of active parameters in the 6-series sonde. Optional high memory (1.5 mB) would make it possible to easily upload the data from 7 sondes, each of which have data files of approximately 75 days at a 15-minute sampling interval.

Battery Life :

Approximate battery life for typical sampling applications with 4 alkaline C cells – 3 hours of

“on” time per day for 0.5 month (10 working days) with the meter powering a 6600 sonde with all

probes active.  Approximate battery life for typical sampling applications with rechargeable battery pack – 3

hours of “on” time per day for 0.2 months (4 working days) with the meter powering a 6600 sonde

with all probes active. Battery capacity restored completely with a 6-hour charge and charged to

approximately 85 % with a 2-hour charge.
