500N Digital Force Gauge Push Pull Gauge Portable Force Meter with Units N/LB/Kg/Oz, Storage Case, Auto Backlit LCD, Auto Power-Off for Teaching School Lab Mechanical Physics (ZMF-500N)

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.

Using it to pull-test adhesion of glass fused to brick. Does exactly what I need holding the highest break-away reading. When I worked in the semiconductor industry I had to make my own recording pull-tester using a bathroom scale and computer to test thin film adhesion to silicon wafers. Wish I had one of these then!

I have a Lyman for trigger pull weight and it tops out at 12 lbf. I need more than that for DA revolvers so I purchased this item. In the range in which I can compare to the Lyman, the are in near perfect agreement.

Product works well and is sold at a good price. However, the listing shows the mounting holes on the back 40 mm apart. That is not correct. I had to throw out the mount I 3D printed, change the design and print a new one with the right dimensions. That time spent has a cost. The real dimension is 41 mm. If they fix the listing, I would increase my rating.

I used it to measure compression and tension on a few projects, and it worked well.

I have two of this brand and very happy

Wide range of force measurability and high resolution.

Operates as advertised.
