BAOSHISHAN Digital Force Gauge 500N Push Pull Gauge 500N/110LB/50Kg/1800Oz Trigger Pull Scale with 4 Units Portable Storage Case Backlit LCD Auto Power-Off for School Teaching Mechanics Experiments

Made a quick and dirty gauge for work and 3D printed & tapped an attachment for the gauge. It is built well, easy to use, accurate and functions as expected. Great value for a check gauge!

This gage is good value for money. You probably want to mount it to something to get a steady reading. When you have it mounted and under a steady load, the reading will drift a bit with time. If the point of the exercise is the characterize the loads in a system, this doesn't matter. if you are trying to calibrate another device, you need something better.

This little machine performed perfectly, and the handy heads for the unit and included hardware for mounting on a test rig made setup and use a breeze. Highly recommended for ease of use!

Accurate enough for my needs. For the price, you can't beat it.

Easy to use and good precision and repeatability. Only headache is the threads on the unit and the adapters are not very good. Most only thread on half way at best. Easy to chase the threads and retap with bottom taps. Just sad you need to do that.

Not for orthodontics

This is a solid force meter with a substantial capacity of up to 500 N or about 110 pounds. It is compact, sturdy and easy to hold, and comes with the accessories needed for both tension and compression measurements. A plastic carrying case is also included. Four M4 screw inserts are on the back to enable mounting it to a stand. I have no directly comparable device to evaluate accuracy but on the kg scale, it agreed with a calibrated electronic scale with a difference of about 0.5% using a 750 g mass which is in agreement with the stated accuracy of < 1%.The precision did not seem quite as good. Ten successive measurements in Peak mode of the force needed to depress a pipette plunger and zeroed after each measurement ranged from 10.3 to 11.6 with a coefficient of variation of about 4.2%. However, it is difficult to exactly duplicate the force application by hand and that might have been the primary contributor to variability. At any rate, a value within the range obtained in this case is good enough for my purposes.This is a useful tool and it is the least expensive force meter I have seen. It seems to be reliable and should function quite well for typical applications. There are a few aspects that I would change if I had the opportunity. For one, the character display for settings is relatively primitive and looks like an ancient LCD calculator. Some setting names formed from display bar segments are peculiar and their meaning is not always immediately obvious without reference to the manual. The display has a narrow vertical view angle and seems to disappear if you use it above or below the direct line of sight.There are several settings that can be entered although apparently not saved such as default ranges and the like, but accessing and using them is rather complicated. Although labeled Set, Peak, Zero and Unit, the buttons have multiple other functions such as to increment or decrement a value depending on what is being set. Reference to the manual and a lengthy flow chart description was needed to enter changes. However, the meter always defaults to direct, continuous mode, and the only options I ever use are setting the Peak function and zeroing which is simple. Units can also be changed easily.This meter seems intended to mainly be used while holding it and the shape is comfortable in hand. However, any measurements attempted with the device simply placed on a surface may suffer from the rounded bottom which allows it to rock in place. Using the attachment screws and a test stand would resolve that nicely although the stands are rather expensive. The meter has a time settable automatic shutoff to save the batteries, but this did not seem to work when in the Peak mode.Perhaps the feature I would most like to see is digital data output but that is something that is only available on much more expensive units. Overall, given its relatively low cost, this force meter provides a very useful tool and should be a good choice.

I love that there isn't any perceived spring or movement on the gauge itself. It feels solid as a rock, yet it can still measure extremely tiny amounts of force.The threading for the adapters is a M6-1.0. Even if the included adapters aren't what you're looking for, you can easily make something that can accommodate your needs yourself. What they have is more than enough for what I'm looking for.The numbers are easy to read, and it has an arrow on the side to identify if it's measuring pull or push (in the even that that would be necessary). By default it shows the current output, but the peak button allows me to see the maximum measurement for a varying load. It has a settings button that allows me to set things like backlighting and max peak, but everything out of the box was the way I wanted it so I didn't really mess with it.The whole thing is fairly intuitive and easy to deal with. It's very accurate, and it comes with a certificate to prove it's readings.Overall a great gauge.Highly recommended.
