The Apera PH60-HF (AI3729) is a professional handheld pH meter designed for measuring hydrofluoric acid (HF) and other strongly acidic solutions. It features the Swiss-made LabSen 835 electrode with an HF-resistant glass membrane and Silver Ion Trap reference system to reduce corrosion, acidic measurement errors, and junction clogging. Its IP67-rated body, automatic calibration, and stable-reading recognition also support routine nutrient-solution testing.
