Challenge Technology provides respirometers to the industrial and research commumity for a variety of scientific applications. Our popular AER-200 aerobic/anaerobic respirometry system, first developed specifically for the measurement of Oxygen uptake in wastewater samples, now is known to be an excellent choice for a variety of aerobic or anaerobic processes. Applications include measurement of most respired biological gasses (Hydrogen, Methane, Co2 and others), and the measurement of respired gases in biofuel and biogas production. It is also the most flexible system on the market. It can accommodate a range of reactor bottle sizes, from 125ml up to 1 liter. And, it is able to grow with your needs, with systems available for monitoring either 8, 16, or up to 24 reactor bottles through one computer system.

Challenge Technology also offers the AR-295 Soil/Compost Columns for the study of respiration in solids. This system is designed specifically for use with the Challenge Technology Rare Earth magnetic stirring base, water bath, and temperature control system.


Challenge Environmental Respirometers are field-proven. There are over 200 units currently in use around the world.

"I have found the performance of the Challenge AER-200 to be unmatched. The precise measurement of oxygen consumption, homogenous mass transfer of test materials, and constant and consistent operating temperature have enabled me to obtain extremely accurate test results, particularly as compared to other respirometer systems. I find the Challenge system to be extremely user friendly."
