The YSI ProSolo meter features digital luminescent optical DO technology. This advanced technology requires no warm-up time and eliminates interference from common gases like hydrogen sulfide, increasing meter accuracy. It stores your calibration data, letting you use the probe with other ProSolo meters without recalibration.

Meter features a large backlit color display that shows measurement reading, status, date and time, and battery level. A separate message area communicates status messages, error messages and information about selected functions in one of 10 user-selectable languages. Alphanumeric entry lets you describe up to 100 sample sites, users and more. A visual and audible stability indicator lets you know when your measurement is stable.

Mil-spec connectors and waterproof IP67 housings make this meter virtually indestructible. For added convenience, it's powered by a rechargeable battery.
