Portable pH Meter for Wine Must and Grape Juice HI99111 

The Hanna Instruments HI99111 is a durable, waterproof, and portable pH and temperature meter designed specifically for measurement of juices including grape juice and wine must. Automatic calibration is performed at one or two points with two sets of buffers. The calibration buffers include a pH 3.00 calibration point instead of pH 4.01 in order to better bracket the expected pH value. All calibration and measurement readings are automatically compensated for temperature variations. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions. The HI99111 uses the HI1048D glass body, amplified pH electrode that offers numerous features that improve pH testing for a variety of juices with a high solids content.
