Troubleshooting Tip: You can decide how many calibration points you use (one, two or three points). The meter automatically detects the calibration solution used. The pH 7.00 solution must always be used as the first calibration point. The meter has a self-diagnosis function. "Er1" is displayed: when the reading exceeds the detectable range of the meter. "Er2" is displayed: the measurement was not stable when you pressed [Cal]. Wait for [Smiley] when measuring, before pressing [Cal]
NOTE: If you find white crystals inside or outside the electrode cap, this is completely normal. It is the 3M KCl that crystallizes over time. Simply rinse it and use the gauge as usual
Large LCD displays pH, temperature and calibration status
Easy calibration with automatic buffer detection
Complete set including calibration solutions, batteries and lanyard in a handy carry case
Automatic temperature compensation (ATC) (in the range 0-50°C)
ATTENTION: water droplets are added during production to maintain the moisture of the electrode. A damp electrode cap does not mean that the product has already been used
