SO-120 Sensor Oxígeno O2 de Referencia para Suelo con Termopar

Sensor que mide la cantidad de Gas Oxígeno (O2) en el Aire y en suelos.
Sensor de tipo célula galvánica. Incluye opción para medir bajo tierra y 5 metros de cable. (Tipo Termopar).

Apogee oxygen sensors are designed to measure 0 – 100% oxygen and come with tinned leads to connect to a datalogger. The SO-120 is designed for use in soil applications with a larger signal, slower response and longer life. It comes with a thermocouple wire to correct for temperature changes. In applications with high humidity, condensation can occur on the Teflon membrane, blocking the diffusion path of the sensor. To prevent this, a resistive heater is included to raise the temperature of the membrane approximately two degrees above ambient temperature. Select a diffusion or flow-through head if needed depending on your application. The sensor is calibrated to ambient air making it very easy to calibrate. An aluminum housing that is filled with epoxy allows the sensor to withstand harsh conditions.
