Combined Optical Sensors

Combined optical oxygen, pH and temperature sensors are ideal for simultaneous multi-analyte measurements. Available in a variety of pairings, the combined sensors are ideal for a number of applications including small scale metabolic rate and respirometry measurements, true temperature-compensated respiration rate measurements of cell cultures or bacteria, O2 monitoring in enclosed gas and aqueous samples, and many more.
