Product information "Force gauge from 3N to 25N"

The spring scale is a measuring device that uses the extension of a coil spring in combination with a spring force gauge to measure a force. The spring scale determines the mass via the weight of the measuring object and displays this on a scale in Newtons. This makes the measuring device ideal for demonstration purposes in physics lessons, for the laboratory or for weighing on site. The force gauges have a robust housing made of aluminum tube with a colored anodized, abrasion-free scale with high resolution. The force gauges are characterized by very high precision: maximum deviation ± 0.3% of the attached load. The taring range is 20% of the maximum weighing range. A hook serves as the load-bearing device.

With the optional compression force conversion kit, you can quickly convert from the measuring function for tensile force to a device for measuring compression force.

Conversion to a compression force gauge in 20 seconds

Using the easily adaptable conversion set, you can also measure compression force with the spring scales.

  Pull off the bracket with the ring to the side. Equip the pressure rod with the tip as desired (M2 thread). Insert the pressure rod into the scale and screw it in well.
Insert the hook screw into the cover, put the plastic handle over it and tighten it with the M4 nut. The hook screw without the plastic tube is used for fastening in machines, etc. If only pressure is used, pull the lower suspension off to the side. Measurement: The pressure rod must always be at a right angle to the measuring surface.
