Building on the base kit, this configuration adds the R3000SD meter with its pH and ORP electrodes plus a pair of calibration buffer solutions (pH 4.01 and pH 7.00) so the probe can be verified and calibrated on site. Like the rest of the R3000SD line it records pH and ORP values to a removable SD card with selectable sampling rates and automatic temperature compensation. Everything ships in a soft carrying case with batteries, backed by a one-year warranty.
