Revolutionizing respirometric testing
OxiTop® is a range of laboratory respirometers from WTW that utilize pressure measurement to determine Biochemical Oxygen Demand (BOD). Ideal for wastewater treatment plants, environmental labs, and biodegradability testing, OxiTop systems automatically track oxygen consumption through pressure changes in sealed chambers. This manometric respirometry method provides simple, accurate, real-time BOD results without manual DO measurements and complex BOD calculations - streamlining compliance, reducing errors, and accelerating testing across diverse water quality applications.
