The HI99121 meter features a large multi level LCD screen which displays both pH and temperature readings simultaneously with 0.01 pH resolution and an accuracy of ±0.05 pH. The LCD screen also has indicators for calibration status and stability, as well as on-screen tutorial messages. The HI99121 has many advanced features that are found in more expensive portable instrumentation including automatic calibration, buffer recognition,and temperature compensation.
