? WHAT IS THE SHOCKMASTERS > ή AREA OFRESPONSE? Shockmaster > is a low cost, compact mechanicaldevice which may be installed on delicate equipment to monitor excessive shock and vibration, thereby assisting inthe detection of hidden damage. When a container isopened, following shipment, there may appear to be no damage. However, if the Shockmaster The Shockmaster > ή has a hemispheric response: itindicates shocks from all directions radial to the unit, axial shocks to the base from beneath, and shocks from alldirections between these planes (see Figure 2). It will notregister axial shocks applied...

It isintended to be packaged with delicate equipment in boxes, crates or containers. If the indicator is trippedӔ when the container is opened, it is evidentthat excessive shock has been experienced, andtherefore the shipment should either be rejected or special inspection procedures should be carried out. > ,...
