There are many factors that cause product damage and losses during transportation, such as poor packaging or improper loading and unloading of goods. Sometimes the receiver cannot tell whether the internal product is damaged from the external package, especially those large goods, such as precision equipment, etc.
Why can’t traditional shock stickers improve the quality of transportation?
The traditional shock stickers cannot record the exact time of the impact. Without relevant information about the timing of impact that happened, it is impossible to infer the location of the accident and handler, and it is difficult to look into the responsibility for the product losses, especially for expensive goods, server, Industrial Computer, LCD screen, Wafer, these losses are even more difficult to estimate.
What is Shock Timer?
Shock timer is one kind of vibration monitor device, it is a disposable product developed by Japan JBL, and made in Taiwan. Its advantage is to show out the passed time on the LED monitor after start-up. When the cargo was shocked or impacted, the timer stopped going at the timing, and then the handlers can infer from it where and when the impact happened. It helps to confirm who is responsible.
There are only two types of shock timer: A-25 and A-50. In other words, it can only provide the detection of the two impact force G values, which have fewer choices than traditional impact indicator labels.

Summary
The Shock Timer has the following 2 great advantages：
1. On-Off Design to prevent activation error
2. Display the time of impact, and then infer the time and location of the damage.
