The YSI® Professional series provides plug-and-play capabilities to give you a meter with as much functionality as needed. Build your own system by ordering the meter, probe(s), and cables(s) you need without having to purchase additional meters or unnecessary accessories.
Easy-to-use meters feature graphic display with detailed messages and instructions that translate to less time reading manuals. Rugged rubber over-molded case protects meters during use. Meters are IP67-rated and are waterproof, even without the battery lid.
The DO meters accept either classic polarographic or “instant-on” galvanic DO sensors with screw-on membrane caps for ease of maintenance. These meters also feature selectable two-point DO calibration and automatic barometric compensation for greater accuracy.
