- Challenge OLR Respirometer
The Challenge OLR Respirometer is a true   "on-line" respirometer which gives oxygen uptake rates for treatment plant operations.   Oxygen uptake in aerobic applications can be measured in batch, sequential-batch, or continuous modes at rates in excess of 150 mg/l/hr.
When you use the Challenge OLR Respirometer, here's what you get: Instantaneous response to changes in influent wastewater characteristics Continuous monitoring of oxygen uptake rate in the mixed liquor of your activated sludge process Capability of operating in batch, continuous, or continuous modes...maximizes the diagonistic capabilities of the OLR respirometer Ease of operation...easy set-up, easy cleanup, and user-friendly software Remote readout and operation through modem connections
