YSI pH, Salinity & Conductivity Meter

Multi use instrument. Capable of measuring DO, pH, Conductivity, ORP, Ammonium, Nitrate, Chloride, Salinity, Total Dissolving Solids and Barometric Pressure, depending on what probe is connected to the instrument. 2000 data-set memory with GLP event logging. Also interval or single event logging capability. Rugged construction with IP67 waterproof case. The meter incorporates a back lit display and keypad. The graphic display comes with a detailed Help. * Temperature range: -5 to 70ºC. * DO: Range 0 to 500%.
