The Apera PH60-WW (AI3721) is a professional handheld pH meter designed for wastewater, coco runoff, organic nutrient solutions, slurries, emulsions, and other particle-rich liquids. It features the Swiss-engineered LabSen 335 electrode with an open junction and polymer electrolyte to prevent clogging and measurement drift. Its IP67-rated, floatable body and replaceable electrode make it suitable for demanding commercial cultivation environments.
