Handheld pH meter HI99171

The Hanna Instruments HI99171 is a durable, waterproof, and portable pH and temperature meter designed specifically for leather and paper analysis. Automatic calibration is performed at one or two points with two sets of buffers. All calibration and measurement readings are automatically compensated for temperature variations. The HI99171 uses the HI1414D glass body, amplified pH electrode that offers numerous features that improve pH testing for surface measurements. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.
