Overpressure Meter – HK Instruments YM-3 Series


  • Field adjustable zero point calibration
  • Pressure limit stickers
  • Robust structure

The YM-3 is used to measure and monitor internal overpressure between shelter and outside area. Reference pressure is measured outside via copper hose lead through special blast and gastight proof wall sleeve. The YM-3 overpressure meter 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 Technical Research centre of Finland/VTT that performs type inspecting mandated by the Finnish Ministry of Interior. The is YM-3 is protected against blast shock and static pressure loads.
