The XL-series offers you the advantages and versatility of having a research-grade pH, mV, ion, conductivity, and dissolved oxygen meter, all in a single instrument. It offers 1000 datapoint memory storage along with bidirectional RS-232. Password security protects your data from accidental deletion. pH mode accepts standard BNC glass electrodes as well as accuFet electrodes directly, and allows for up to five-point pH calibration. ISE mode offers direct and indirect measurements, known and analyte, addition and subtraction methods. Conductivity mode accepts two-cell and four-cell probes. The XL-60's DO mode calculates 5-day BOD testing, OUR, and SOUR with automatic salinity and barometric pressure compensation.

What's included: meter, accuTupH+® calomel, combination pH electrode 55502-04, ATC probe 94000-62, electrode support arm and bracket, 110/220 power supplies, and operation manual. 59331-65 also includes self-stirring BOD probe 53109-50.
