The Apera Instruments PH8500-SB Portable pH Meter is designed for measuring strong alkaline solutions. The equipped Swiss LabSen® 841 pH Electrode adopts a special H glass membrane, which is ideal for measuring strong alkaline solutions (up to pH 16.00) and high-temperature solutions (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 PH8500-SB Portable pH Meter has a ±0.01 pH accuracy in a range of -2.00-16.00 pH, and Temperature Range: 0 to 100°C(32 to 212°F), Auto Calibration with auto recognition 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.
