YSI PRO Series 1020 - Dissolved Oxygen, pH/ORP Meter
The YSI Pro1020 is a rugged handheld meter that measures dissolved oxygen and temperature alongside pH or ORP (redox). Choose a Polarographic DO sensor for long sensor life, or a Galvanic DO sensor for immediate sampling with no warm-up. IP-67 waterproof, 1-meter drop tested, and EPA-approved for drinking water and wastewater compliance reporting.
Instrument only. Requires a ProSeries 1020-x field cable (1, 4, 10, or 30 meter) — select your cable length below — plus a DO sensor and a pH or ORP sensor, both sold separately.
