The Morelli Force Gauge Dynamometer — 25 to 250 gf (cN) is a mechanical tensiometer reading traction from 25 to 250 gf (cN). Its scale is concentrated where biologically light orthodontic loads live, so small differences in delivered force can actually be read. The instrument is built with a stainless steel body and polymer tips and carries a blue scale.
Key Features
25 to 250 gf (cN) measuring range — a scale dedicated entirely to light-force measurement.
Better discrimination at low forces: because the full scale is devoted to light loads, values below 250 gf (cN) are spread across the whole face rather than crowded at one end.
Two tips for easy positioning allow the gauge to be engaged on either side of the arch without repositioning.
Mechanical operation with no batteries or electronics, read directly at chairside.
Blue scale color identifies this light-force instrument immediately on the tray.
Corrosion-resistant construction in stainless steel with polymer tips for repeated reprocessing.

Clinical Applications
Light elastics and elastomeric chain — measuring the traction of light elastic prescriptions and elastomeric chain, whose working loads sit in the lower half of this scale.
Coil spring activation — checking the load produced by open and closed coil springs, which are typically activated within the 25 to 250 gf (cN) span.
Intrusion and initial alignment — verifying the light, continuous forces used for intrusion and early alignment, where reading small force differences is what matters.
How small a force difference can you actually read?
With the whole face devoted to 25 to 250 gf (cN), light elastics, elastomeric chain and coil spring activations are read where resolution matters more than reach — a direct value from the blue scale, taken at chairside with no power source.
