The 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 3-in-1 Glass pH/Temperature Electrode adopts a special HF glass membrane, which is resistant to HF corrosion, and is capable of measuring solution containing HF for about 1000times. (test condition: 25℃, 1% HF concentration, test period 1minute)
It’s also working 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).
ThisPH8500-HF Portable pH Meter has a ±0.01 pH accuracy in a range of -2.00-16.00pH, and Temperature Range: 0 to 100°C(32 to 212°F), Auto Calibration with autorecognition 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 2-year warranty (6 months for the electrode).”
