It can generally be observed with the naked eye, but it is not particularly accurate. To prevent the explosion-proof membrane from aging, it is possible to supply water flow to it in order to avoid damage caused by high temperatures.
The best solution is to replace it; it’s fine for negative-pressure furnaces, but not for positive-pressure furnaces. The thickness of the graphite sheet must be taken into account, as it is proportional to the hydrogen chloride pressure it can withstand.
