Review: Zeppin Racing Digital Spring Gauge - ZR-SG1

Zeppin Racing Digital Spring Gauge
This is a handy tool to have on the shelf. I have found it to be good quality, reasonably accurate, and has a low price. Its not a tool that you use everyday, but it is a must if you need to test springs.
Springs degrade over time and they need to be checked. It is really helpful when you:
- have several springs and you need to figure out what the rates are to match them up
- or you have a pair of springs and you want to be sure that they are both the same rate.
This tool works on 5-14v dc, and can measure:
- N/mm
- N/cm
- Lb/in
- gF/mm
