Photometer for Tartaric Acid in Wine

The HI83748 Photometer for Tartaric Acid in Wine combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the concentration of tartaric acid in wine within a 0.0 to 5.0 g/L (ppt) range using the HI83748-20 ready made reagents.

Built-in timer - Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.

Zero key - A simple press of the zero key on the face of the meter will account for the color and imperfections in the wine sample before reagent addition.

Auto shut-off - Automatic shut-off after 15 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally left on.

Battery status indicator - Indicates the amount of battery life left.

Error messages - Messages on display alerting to problems including no light, inverted sample, and out of range.

Units of measure - Appropriate unit of measure is displayed along with reading.
