YSI Model 52 Dissolved Oxygen Meter

Based on the classic YSI design that has become an industry standard for years, the Model 52 has a unique combination of accuracy, ruggedness and flexibility. Microprocessor controls make the Model 52 one of the most accurate YSI Models available. With up to 70 storage points in non-volatile memory, the Model 52 can record DO, time and temperature readings and send them directly to an RS-232 serial printer or personal computer. Each reading is automatically compensated for temperature, with direct salinity compensation from 0-40 PPT to cover the full range from fresh to salt water. The large LCD simultaneously displays DO in % air saturation and mg/L, temperature and time of day. For full protection, the 52 is also enclosed in a rugged, water resistant case.
