YSI Professional Plus Handheld Multiparameter Instrument

The YSI Professional Plus provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium, nitrate, chloride and temperature.

The Pro Plus instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on.

Data management can become a daunting task over time but with the Data Manager software this task is much simpler and efficient. Download data, configure instruments, and conduct real-time studies easily with Data Manager software. View data graphically or in tabular form and export data as needed to other programs. Data Manager software is a very powerful tool. So powerful in fact, that we give it to you at no charge when purchasing a Pro Plus. After all, it's all about the data!
