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
2000 hours operating time

This pH tester is compact and lightweight, very easy to carry.
Multifunctional 5-in-1 pH meter water: this digital pH meter water can test PH/TDS/EC/temperature/salinity. Measuring range for pH: 0.01-14.00pH (accuracy ± 0.05pH). TDS: 0 to 1000ppm, 1000ppm to 10000ppm, 10.1 to 200.0ppt. EC: 0-10000uS/cm, 10.01-19.99ms 20.1-400mS/CM Temp. 60.0°C, 32.0-140°F. Salt content: 0.00 to 25.00%. The backlit display can be adapted to a variety of lighting conditions.
Ideal for home and aquarium: drinking water: pH meter water is optimal at 7.4, TDS value should be below 50, EC should not exceed 0.5 ms/cm to ensure the purity of the water. Swimming pool: ideal pH value 7.2-7.8, SALT value at 0.27%-0.34% (2700-3400ppm), TDS value 400-1500ppm, temperature 25℃-29℃. Aquarium: freshwater fish pH standard is 5.5-7.5, salinity standard is 0.1%-0.3%; saltwater fish pH standard is 8.0+, salt content standard is 1%-3.5%.
Green illuminated display and removable probe: the display of this pH meter is backlit to ensure that you can read the results in low visibility. (Auto shut off: switches off automatically after 5 minutes of stand-time.) The removable design of the probe prevents accidental damage to the probe and increases replacement costs, you can easily replace the electrode probe yourself.
