SpotSee MAG 2000 Impact Indicators are cost-effective, resettable and reusable devices for monitoring the handling of fragile goods and freight containers greater than 500lbs. The devices are used on rail cars and trucking fleets to monitor for excessive impacts during humping or latching. The MAG 2000 is used on products or product packaging. It’s ideally placed on the product since the impact experienced by the product itself, is generally more important than the impact received by the packaging. The placement of the MAG 2000 will affect the selection of the proper sensitivity.
