Combination Water Meter Kit with Dissolved Oxygen Probe

This Multi-Purpose Water Meter can Measure Dissolved Oxygen (DO) , pH, Conductivity, TDS, Salinity or Temperature Using Different Probes. The kit includes includes one DO 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. This meter is the ideal tool for numerous professional water testing applications including: aquaculture, laboratories, swimming pools, spas and water treatment facilities. 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 ℃/℉ is switchable 1 hour auto power off #850048DOK Kit includes: Combo Meter, DO Probe, (2) Heads, Battery, Manual, Hard Carry Case  Specifications Model 850048 pH Measuring Range 2.00~12.00 pH Resolution 0.01 pH Accuracy ±0.1 Conductivity Measuring Range 0~199.9, 0~1999 us/cm  0~19.99, 0~150.0 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 0~199.9*f, 0~1999*f ppm 0~19.99*f, 0~150.0*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 0.30~1.00 Salinity Measuring Range 0~10.00 ppt, 0~42.0 ppt (SEA Water) Salinity Resolution 0.01 ppt, 0.1 ppt Salinity Accuracy ±1% of F.S ±1 digit D.O.
