Hanna Instruments has launched a new line of portable pH meters for testing milk, meat, yoghurt and cheese.
As part of the Foodcare family, the meters include a general-purpose model (HI98161) and versions for milk (HI98162), meat (HI98163), yoghurt (HI98164), and cheese (HI98165) products.
The pH of food can influence taste and texture and indicate its potential for spoilage, and the meters allow for a log of measurements that can then be transferred to a Windows-compatible computer with the supplied USB cable and software.
Good Laboratory Practice (GLP) data which includes calibration date, time, offset, slope, and buffers used is also transferred with logged readings for increased traceability.
The data can be reviewed at any time with the push of a button to confirm acceptable pH electrode performance.
With the Cal-Check feature, the user is alerted if the electrode needs to be cleaned, or if buffers are contaminated.
After calibration, the overall condition of the pH electrode is displayed as a percentage. The overall condition is based on the offset and slope characteristic of the pH electrode.
Each meter is supplied with an application-specific pH/temperature probe, calibration buffer, cleaning solution, USB cable, and software packaged in a rugged carrying case that is thermoformed to hold everything in place.
