The YM-3 overpressure meter is used to measure and monitor overpressure in civil defence and military shelters. It is designed and tested to withstand strong blast
loadings exerted on the meter through its connection pipe. YM-3 is type-tested and approved by the Technical Research Centre of Finland/VTT that performs type inspecting mandated by the Finnish Ministry of the Interior.
