Impact monitoring for high-value freight.
Impact Register manufactures mechanical impact recorders that document the shocks and vibrations your freight experiences in transit. We are the source of truth. G-force sensing needs no power or signal; a battery powers the chart-drive motor. The Savage Impact Register patent was issued in 1915, part of our history of mechanical impact monitoring.
Industries we serve
Six industries where high-value freight, long routes, and tight handling tolerances call for reliable in-transit monitoring.
Power & Energy
A large power transformer that shifts its core in transit can take a year to replace. Impact Register gives you the peace of mind you need to energize after transportation.

Defense
Monitoring for sealed articles, RF-restricted cargo, and routes that cannot be disclosed.

An objective record of transit conditions, shared by shipper, carrier, and consignee, calibrated, documented, and readable by all three.
How the record holds up →Two recorders for high-value freight
The RM-3WE and GEMM are the continuous, multi-axis impact recorders at the center of our line, each writing a complete, time-stamped record of transit conditions, with no power needed for G-force sensing and no signal required. A battery powers the motor that advances the chart.
RM-3WE
The complete record of everything your shipment endured: in three axes, for up to 120 days. G-force sensing needs no power; a single C cell powers the chart-drive motor.

GEMM
Every shock, drop, and vibration, when it happened, how far it fell, and which corner hit.

More than a century of manufacturing experience
In 1915, William P. Savage received U.S. Patent No. 1,125,731 for the Impact Register. From rail-era freight to missile nose cones to today's satellite and semiconductor moves, Impact Register has been writing the record for more than a century.
