Apera PH700-WW Benchtop pH Meter – Wastewater, Slurries & Dirty Liquids

Apera Instruments PH700-WW Benchtop pH Meter

Engineered for the toughest sample matrices in the lab — the PH700-WW pairs Apera's proven benchtop platform with the Swiss-made LabSen® 333 pH/Temp. electrode, purpose-built for dirty liquids including wastewater, suspensions, emulsions, and slurries. Get fast, reliable pH readings without clogging or reference contamination.

Why Choose the PH700-WW?

Swiss LabSen® 333 Open-Junction Electrode — open junction design with long-life reference system resists clogging in particulate-heavy and high-turbidity samples
±0.01 pH Accuracy — reliable across the full 0–14 pH range with ±0.01 pH/3h stability
3M KCl Electrolyte — standard, robust reference electrolyte suited for wastewater and industrial sample matrices
1–3 Point Auto-Calibration — self-diagnosis and electrode condition display for traceable, confident results
Max/Min Reading Mode — capture peak and trough values during dynamic measurement periods
50-Set Data Storage — log measurements with numbering, unit, temperature, and ATC status
IP54 Spill-Proof & Dust-Proof — built for real-world lab and field-adjacent conditions
Dual Electrode Holder — accommodates up to 2 electrodes simultaneously

Ideal Applications

Wastewater treatment and environmental monitoring
Suspensions, emulsions, and slurries (industrial process QC)
