The Apera PH700-WW (AI5012) is a laboratory-grade benchtop pH meter specifically designed for testing dirty, turbid, and particle-heavy liquid samples, including wastewater, suspensions, emulsions, and slurries. It comes with the Swiss-engineered LabSen® 333 combination pH/temperature electrode, which features an open-junction design and solid polymer electrolyte to reduce clogging and contamination commonly experienced with conventional pH probes. Its corrosion-resistant POM electrode body and hemispherical blue-glass sensing membrane are designed for durability and reliable measurements in demanding sample conditions. The meter provides ±0.01 pH accuracy, automatic temperature compensation, automatic calibration, and built-in data storage. These features make it suitable for laboratory quality control, complex nutrient mixtures, coco-coir runoff, wastewater analysis, and general water testing.

Key Advantage: The Apera PH700-WW combines laboratory-grade pH measurement with an open-junction electrode designed to resist clogging in dirty and particulate-heavy samples. Unlike conventional probes that may require frequent cleaning or replacement when exposed to slurries and suspended solids, the LabSen 333 uses a solid polymer electrolyte that requires no refilling. Its ±0.01 pH accuracy, electrode-condition diagnostics, and 50-record data storage make it particularly useful for laboratories and commercial cultivation facilities that need reliable measurements of complex liquids and traceable quality-control readings.
