A compact, self-powered platform for real-time wave monitoring, the CB-75-SVS features a 21″ hull diameter, under 40 lb weight, and three integrated 4 W solar panels. It combines the SeaView Systems SVS-603HRi inertial wave sensor with the NexSens X3-SVS data logger, offering wireless telemetry (Wi-Fi/4G LTE/Iridium), three 1.5″ pass-through ports, mooring eye nuts, and optional expansion for additional sensors.The YSI Pro20i is a rugged, easy-to-use handheld dissolved oxygen meter designed for reliability in the field. The Pro20i, with an integrated (non-detachable) cable, it's a direct upgrade to the legacy Model 55 and 550A. Ideal for wastewater applications, it's EPA-approved for DO compliance reporting. The Pro20i comes complete with instrument, cable, and sensor—everything you need for fast, accurate oxygen measurements.
