- The Combo is delivered complete with protection cap, a probe replacement tool and four 1.5V batteries
- The double display shows pH/EC or TDS/temperature
- Automatic calibration at one or two points
- Stability indicator
With a waterproof case, this instrument measures four different parameters: pH, conductivity, Total Dissolved Solids (TDS) and temperature. Neither change of probe, nor intermediate calibration are necessary. pH, conductivity and TDS measurements have an automatic temperature compensation.
