Mxmoonfree 50N Digital Force Gauge Push Pull Gauge Portable Force Meter with Units N/LB/Kg/Oz, Storage Case, Auto Backlit LCD, Auto Power-Off (ZMF-50N)

I gave the product 5 stars because it's very accurate and well packaged. One important thing to consider is the range of force you need to measure. I'm working with very small springs and needed to know some details for records. I first bought the 5N model, but its max range was right near the point I needed to measure so I just ordered the 50N model and it showed the spring to be about 2 lbs of force which is just over the 5N max models limit.

As described

引っ張りの測定をするときに本体を引っ張ると、裏の電池蓋が簡単に外れるので使いずらいです。ちょっと緩いのではなく、ほとんど引っかかりがないです。測定機の電池蓋が引っ張り強度NGです・・。

This works great. It does both push and pull force. I am a big fan that you can toggle between peak and momentary force readings.

I needed a small handheld pull gauge for work (non destructive testing) so I figured I would give this a try. I’m testing to 70lbs so this tester fit that need. Easy to set up, easy to grip and easy to see the display. Good case and accessories that comes with the tester and is very accurate (had unit tested in a lab for accuracy). Overall this was a great purchase
