Packaged for convenience, the combination of the YSI 650 MDS and YSI 600R sonde allows you to collect 8 simultaneous parameters in real-time. Designed for reliable field use, the display and data logger features an IP-67, impact-resistant case. The YSI 650 MDS can display all the parameters simultaneously, including date and time. The display autoadjusts the contrast making it easy to read.
