Multi-Probe System 556 (YSI)

The standard model measures dissolved oxygen, pH, conductivity, temperature, and ORP. 
The YSI® 556 simultaneously measures dissolved oxygen, pH, conductivity, temperature, and ORP and is capable of measuring salinity. Housed in an IP-67, impact-resistant case, the meter offers an easy-to-read screen and can store over 49,000 data sets, time and date stamped. Measurements are easy with field-replaceable DO electrode modules and easy-to-use, screw-on cap DO membranes. Comes with a soft-sided carrying case. The instrument is powered by 4 C batteries or an optional rechargeable battery pack (sold separately) with fast charge feature. Three-year warranty for the instrument. One-year warranty for probe module. An RS-232 cable comes with the unit for downloading data to a PC. The YSI 556 is compatible with Ecowatch™ for Windows™ data analysis software. Order the instrument, cable, and accessories separately.

Measurement Specifications: Dissolved Oxygen - Range: 0 to 500% air saturation/0 to 50 mg/L. Accuracy: 0 to 200% air saturation, ±2% of the reading or 2% air saturation, whichever is greater; 200 to 500% air saturation, ±6% of the reading/0 to 20 mg/L, ±2% of the reading or 0.2 mg/L, whichever is greater; 20 to 50 mg/L, ±6% of the reading. Resolution: 0.1% air saturation/0.01 mg/L. pH- Range: 0 to 14. Accuracy: ±0.2 units. Resolution: 0.01 units. Conductivity - Range: 0 to 100 mS/cm. Accuracy: ±0.5% of reading + 0.001 mS/cm. Resolution: 0.001 mS/cm to 0.1 mS/cm (range-dependent). Temperature - Range: -5°C to 45°C. Accuracy: ±0.15°C. Resolution: 0.1°C. ORP - Range: -999 to +999 mV. Accuracy: ±20 mV. Resolution: 0.1 mV. Barometer (optional) - Range: 500 to 800 mm Hg. Accuracy: ±3 mm Hg within ±15°C temperature range from calibration point. Resolution: 0.1 mm Hg.
