NSR NHR-100 Hydrostatic Release HRU for NEB-2000 / NEB-1000 EPIRB

aterial Fiber Usage/Application Marine Brand NSR Weight 500 grams Voltage 240V Operating Mode Yes Tank Size (Litre) Full Model Number NHR100 The Hammar H20 is also used widely for Emergency Position Indicating Radio Beacons (EPIRB). 90% of the world's EPIRB manufacturers are using the Hammar H20 for the freefloat function. Should the vessel sink, the Hammar H20, which is activated by increasing water pressure, will automatically release the EPIRB. On reaching the surface the EPIRB starts to emit a signal of identification and position to a satellite. Instead of the rope sling a specially developed plastic bolt secures the radio beacon and will be cut when the unit is activated. Other methods of securing the beacon are also used, such as a rope or a strap.
