Apogee SO-130 0-30% Oxygen Sensor

The SO-130 has a standard response time of 15 seconds, is designed for use in soil or atmospheric applications, and has high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. It comes with a thermistor temperature sensor to correct for temperature changes and a resistive heater to raise the temperature of the membrane approximately two degrees above ambient temperature to keep condensation from occurring on the Teflon membrane and blocking the diffusion path of the sensor. Typical applications include measurement of O₂ in laboratory experiments, monitoring gaseous O₂ in indoor environments for climate control, monitoring of O₂ levels in compost piles and mine tailings, monitoring redox potential in soils, and determination of respiration rates through measurement of O₂ consumption in sealed chambers or measurement of O₂ gradients in soil/porous media.
