Using the standard sensors – min diameter is 3 inches. However, we can install sensors on the pipes up to 2 inches at high temperatures and even up to 1 inch at normal temperatures. This will require some additional adjustment of the probes but it is possible to install permanent corrosion monitoring sensors to the piping as thin as 1 inch diameter. As for the temperature range, we use the corrosion sensors that operate between -180 °C (-290 °F) up to 600 °C (1100 °F)
