Combination Water Meter Kit with pH Probe

The Sper 850048 Combination Water Meter can Measure Dissolved Oxygen, pH, Conductivity, TDS, Salinity or Temperature Using Different Probes. This kit includes includes one pH probe. Additional probes optional also allow it to operate as a highly accurate pH meter, Conductivity meter, TDS meter, Salinity meter or DO meter as desired.Probes change are easily changed and include specially designed guards to prevent tip damage. Large, backlit LCD can display multiple parameters including: pH, Conductivity, TDS, Salinity, Dissolved Oxygen, Temperature using different probes Displayed parameter is determined by probe type Green backlight for dark environment Fast measuring of Dissolved Oxygen value Accurate, replaceable probes with safety caps Auto ranging conductivity measurement Auto temperature compensation ATC 99 points memories w/recall function Multiple points calibration: 3 points for pH, 1 point for DO, 4 points for conductivity Manually altitude and salinity compensation function for DO measurement Available replacement probes Temperature unit degrees C/ is switchable 1 hour auto power off #850048PHK Kit includes: Combo Meter, pH Probe, pH Buffer Set 3-40ml. bottles - 1 each of pH 4, 7, 10, 2, 4 AA Batteries, Manual, Hard Carry Case Specifications Model 850048 pH Measuring Range 2.0012.00 pH Resolution 0.01 pH Accuracy ±0.1 Conductivity Measuring Range 0199.9, 01999 us/cm 019.99, 0150.0 ms/cm Conductivity Resolution 0.1 us/cm, 1 us/cm, 0.01ms/cm, 0.1 ms/cm Conductivity Accuracy ±1% of F.S ±1 digit TDS Measuring Range 0199.9*f, 01999*f ppm 019.99*f, 0150.0*f ppt f is TDS factor TDS Resolution ±1% of F.S ±1 digit TDS Accuracy 0.1, 1ppm, 0.01, 0.1ppt TDS Factor 0.301.00 Salinity Measuring Range 010.00 ppt, 042.0 ppt SEA Water Salinity Resolution 0.01 ppt, 0.1 ppt Salinity Accuracy ±1% of F.S ±1 digit D.O.
