A YSI 6500 with a YSI 6-Series sonde is a cost-effective alternative for water quality monitoring. With multiple current loop channels, the 6500 is easily integrated with Modbus or SCADA plant control systems and chart recorders. Define setpoints for four parameters and trigger alarms or phone dialer when readings are beyond those setpoints.

Calibrate in the field or in the lab with built-in software. Get flexible with a 650MDS handheld and use the sonde for other applications.

Features:

Continuously monitor DO, conductivity, temperature, and pH
Eight scalable 4-20 mA current loop channels
Four SPDT relays
Calibrate in field or lab
Versatile 6-Series sonde adds flexibility
