Apera Instruments PH8500-HF Portable pH Meter is designed for measuring solutions containing strong acid, solutions containing hydrofluoric acid, and storage battery solutions. The equipped Swiss LabSen® 831 Glass pH Electrode adopts a special HF glass membrane, which is resistant to HF corrosion and is capable of measuring solution containing HF acid for up to 1000 times. (measurement time<1 minute, and HF concentration should be less than 0.1mol/L or 0.2% wt%)

The probe also works well in high-temperature samples (up to 100˚C/212°F). The unique LabSen blue hemispheric glass membrane has a faster response rate, better repeatability, and built tough - highly resistant to general impact (totally differentiates from the fragile conventional glass bulb membrane).

This meter has a ±0.01 pH accuracy in a range of 0-14 pH, and temperature Range: -5 to 100°C (23 to 212°F), Auto Calibration with auto-recognition of up to 12 kinds of buffer solutions, Auto. Temp. Compensation, and supports stable reading/auto-hold display mode. The meter's digital filter technology improves response time and accuracy.

Intelligent Functions: Smart Self Diagnosis reminds of out-of-range measurement, incorrect calibration, and electrode invalidation. Other functions include calibration reminders, calibration date checking, easy parameter setting. GLP standard data management, 500 data sets of storage, manual/auto storage, USB data output.

Reliable Structure Design: Large white backlit LCD; foldable stand allows use as a benchtop meter; soft silicone case gives you a nice firm grip; connector protection cap, IP57 waterproof rating; Powered by 3 AA batteries. The meter is RoHS and CE certified and comes with a 3-year warranty (6 months for the electrode).
