+The probe head needs a constant flow of gas to work correctly. A standing atmosphere over the probe head will inherently dry itself and therefore provide false data.
+Basic gases and fumes will form phosphates with the phosphoric acid (e. g. amines). This leads to the deterioration of the acid which is the reason why the sensor head needs to be cleaned and impregnated with fresh acid on a regular basis.
