Opis
The Mini-OX is an in-situ oxygen sensor for control in low temperature applications. It measures %Oxygen concentrations in the exhaust of furnaces, boilers and other applications and is ideal for package boilers.
The linear analogue output makes the sensor easy to connect to an existing combustion controller, so the air to fuel ratio can be trimmed continuously instead of being set once and left. Calibration can be carried out in normal air and can be triggered externally, which keeps routine servicing short.
Prolonged operation below 0.1% O2 can damage the sensing element. The sensor measures the partial pressure of oxygen in the sample gas, so deviations in barometric pressure from the value present during calibration cause readout errors proportional to the change.
