300N Digital Force Gauge Push Pull Gauge - Portable Lab Meter

Our review of the 300N Digital Force Gauge finds it best suited for teaching labs and light industrial testing where a compact, accurate push/pull meter is required. The single biggest reason to buy is its combination of a 300N range with selectable units and a PEAK mode that reliably captures maximum force, making routine insertion, pull and destructive tests easier to document. It is a straightforward handheld tool that balances accuracy, a clear auto-backlit LCD, and practical power saving for classroom and bench use.

Key Features

• Four selectable units: Switch between N, lb, kg and oz so results can be reported in the unit your class or procedure requires.
• 300N maximum range: A 300N/30kg/65lb/1100oz capacity covers most small push and pull tests without multiple instruments.
• Three measurement modes: Real-time, PEAK and First-PEAK modes give flexibility to record steady readings or capture the maximum force applied.
• Auto power-off and timeout setting: The configurable 0-15 minute auto shutdown reduces battery waste in a busy lab environment.
• Min force shielding: The device can hide readings below 0.5% of full scale to avoid spurious low-value noise on the display.

Who It's For

The 300N Digital Force Gauge is aimed at educators, lab technicians and small-scale product testers who need a portable, easy-to-read force meter for routine pull and push measurements. It is particularly useful in mechanical physics classes where switching units and capturing peak force quickly matters for demonstrations and student experiments.

Those who need ultra-high precision metrology or higher capacity testing beyond 300N should consider a calibrated bench instrument or a gauge with a higher load rating. Users requiring integrated data logging or PC connectivity should look for models with dedicated interfaces, as this unit focuses on handheld simplicity and direct readout.

Pros & Cons
