The Hanna milk pH tester has a specialised conic tipped pH electrode with a glass body. The specialised pH electrode is rugged and easy to clean.Featuring a liquid crystal display, the meter weighs in at 50g and measures 51 x 159 x 21mm. For best results, operate in 0 to 50°C, RH 95% max environment.

The meter has a range of 0.0 to 14.0 pH and a resolution of 0.1pH with accuracy at ±0.2pH @ 25°C. Calibration is automatic at one or two-point. With an easy to change battery facility, the pH tester has an approximate battery life of 1000 hours of continuous use and has an auto-off feature enabled after 8 minutes or 60 minutes.

The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging after measurements in semi-solid or viscous samples.

The glass tip uses a special low temperature glass formulation. This is beneficial since many food products are at low temperature. The open junction design consists of a solid gel interface between the sample and the internal reference wire. This makes it impermeable to clogging after measurements.The conical shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in samples such as milk and yogurt.

Each meter is supplied with: pH 4.01 buffer solution liquid sachet x 2, pH 7.01 buffer solution liquid sachet x 2, cleaning and disinfection solution for dairy products x 2, electrode storage solution 13mL dropper, instruction manual, quality certificate and a protective cap.
