Why measure oxygen partial pressure? The oxygen partial pressure can be used to calculate the water vapor content, that is, the oven is working properly and calculate the current relative humidity in the box. Relative humidity RH% = (WVP ÷ WVPmax) x 100% = {[BP-(ppO2÷0.2095)]÷ WVPmax} x 100% in: WVP...
