The Apera Instruments PH8500-PW Portable pH Meter is designed for professional pH measurement of purified water such asdrinking/RO/distilled/deionized water and other low ion-concentration solutions.The equipped LabSen 803 3-in-1 Glass pH/temp. Electrode adopts a moveablesleeve junction, Long-Life reference system, and a patented pH/temp. dual sensor structure, making precise purified water pH measurement easier than ever. Get stable readings in as quickly as 30 seconds. The unique LabSen blue cylindrical 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).
The meter has a ±0.01 pH accuracy in a range of -2.00-16.00 pH (Temp.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.
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/autostorage, 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 (6months for the electrode).
