Apera PH850-HF Portable pH Meter for Strong Acids and HF Measurement

Apera PH850-HF is a portable pH meter specifically developed for pH measurement in challenging samples containing hydrofluoric acid (HF), strong acids, and battery electrolytes. The Swiss LabSen 831 3-in-1 glass pH/temperature electrode features an HF-corrosion resistant specialized glass membrane, enabling use in solutions with up to 1% HF concentration for approximately 1000 measurements.

The instrument performs pH measurement in the 0-14 pH range with ±0.01 pH accuracy and is capable of operating in high-temperature samples up to 100°C. The automatic calibration function recognizes 12 standard buffer solutions and includes automatic temperature compensation, providing ease of use. The intelligent self-diagnostic feature alerts users to out-of-range measurements, improper calibration, and electrode malfunction conditions.

Suitable for laboratory users who work with HF acid or other corrosive acids and require a durable and reliable field/laboratory pH meter.
