YSI® ProDSS Multiparameter Field Sampling Instrument
The YSI ProDSS (digital sampling system) handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, turbidity, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature along with depth. The rugged and reliable ProDSS allows for the measurement of water quality parameters with digital sensors. The ProDSS uses smart, user-replaceable sensor technology that can be connected in any port and automatically recognized by the handheld while retaining the calibration data.

YSI® 550A Dissolved Oxygen Meter
The YSI 550A D.O. meter is field-rugged and sets the standard for aquaculture D.O. measurement. It is completely waterproof to 1M (IP67-rated), impact-resistant and measures dissolved oxygen to 50 mg/L and 500% saturation. It features a field-replaceable, polarographic D.O. probe that is weighted for quick sinking; easy-to-replace cap membranes, push-button calibration and temperature, salinity (to 70 ppt) and altitude (to 10,000 ft.) compensation. The large backlit display shows simultaneous readings of oxygen, temperature (ºC or ºF), and a low battery indicator.

YSI® ProODO® Optical Dissolved Oxygen Meter
The YSI ProODO® is rugged, easy to use handheld optical dissolved oxygen meter designed for sampling applications. With many benefits over traditional D.O. technologies, the ODO (Optical Dissolved Oxygen) luminescent sensor has no flow dependence, making it the perfect choice for applications where stirring is difficult or undesirable. This also reduces the possibility of operator error, ensuring high quality data. Unit is resistant to probe fouling and interferences from hydrogen sulfide and other gases. The smart digital ODO probe stores calibration data so probes can be interchanged between instruments without recalibration. Stores 5,000 data sets, and USB connection allows interaction with Data Manager software (included). Supports English, Spanish, German, Italian, Norwegian, Portuguese and French.

YSI® Pro Plus Multiparameter Meter
Measure up to 11 different parameters with one meter and only a simple cable change! Meter has a backlit display and keypad, graphic display with detailed messages and instructions plus a gauge that continuously shows the battery level. The rubber over-molded case has an IP67 waterproof rating and is drop rated to 1 meter. Instrument can log data (5,000 data-set memory with site identity and GLP event logging) and download it to a PC. Data Manager desktop software, a communication dock and USB cable are included.

YSI® Pro20 Dissolved Oxygen Meter
Designed specifically for aquaculture, the YSI Pro20 dissolved oxygen meter is a rugged, user-friendly instrument for dissolved oxygen measurement. IP-67 waterproof and rubber over molded case, and 1-meter drop tests ensure the instrument remains in your hands to provide years of sampling even in the harshest field conditions. Choose a D.O. sensor that best meets your needs. Fast response times with the Polarographic or Galvanic dissolved oxygen sensors allow you to complete your sampling routine quickly. The long life of the Polarographic sensor saves time and money and reduces your overall cost. The Galvanic sensor enables you to start sampling immediately without a warm-up period.

YSI® Pro2030 Dissolved Oxygen/Conductivity/Salinity/TDS/Temp Meter
The YSI Pro2030 provides everything you need in a handheld dissolved oxygen instrument with conductivity. Automatically compensates D.O. readings for changes in salinity. User-replaceable D.O. sensors and cables, 50 data set memory and simple D.O. calibration make the Pro2030 user-friendly. Rugged design and 1-meter drop tests ensure the instrument remains in your hands to provide years of sampling even in the harshest field conditions. Fast response times allow you to complete your sampling routine quickly, saving time and money. Your perfect handheld for brackish water and/or applications with varying salinity.
