Apera PH8500-HF Portable pH Meter – Strong Acid and HF Measurement

The Apera Instruments PH8500-HF is a portable pH meter specifically engineered for pH measurement in solutions containing hydrofluoric acid (HF) and strong acid properties. In these aggressive environments where standard glass electrodes deteriorate rapidly, it delivers reliable measurement capability through the LabSen 831 3-in-1 glass electrode, which resists HF corrosion.

The instrument operates across a pH range of -2.00 to 19.99 with ±0.01 pH accuracy and measures across a wide temperature range from -5 to 100°C. Automatic buffer recognition, automatic temperature compensation, and stable reading mode simplify calibration and measurement procedures. With a 500-record data storage capacity and USB output, it ensures GLP-compliant data management.

Intelligent self-diagnostic function alerts users to out-of-range measurements, improper calibration, and electrode faults. With IP57 protection rating and durable soft silicone case, it is suited for field and laboratory conditions. An essential tool for laboratories handling HF and battery electrolyte solutions, chemical manufacturing quality control, and materials testing facilities.
