The Morelli Force Gauge Dynamometer — 50 to 500 gf (cN) is a mechanical tensiometer reading traction from 50 to 500 gf (cN). This is the span that most day-to-day intraoral elastic prescriptions fall into, which makes it a general-purpose gauge for routine chairside verification. It is built with a stainless steel body and polymer tips and carries a green scale for quick identification.
Key Features
50 to 500 gf (cN) measuring range covers the working loads of the intraoral elastics prescribed in routine treatment, with enough resolution at the lower end for lighter prescriptions.
Two tips for easy positioning let the gauge be engaged from either side of the arch, so upper and lower attachments are reached without changing hands.
Mechanical direct reading means no batteries and no warm-up — the value is read straight from the scale during the appointment.
Green scale color identifies this instrument at a glance on the instrument tray.
Corrosion-resistant construction in stainless steel with polymer tips, suitable for repeated clinical reprocessing.

Clinical Applications
Routine intraoral elastic checks — confirming that the elastics a patient is wearing deliver the prescribed force, the most frequent measurement in routine practice.
Space closure and retraction mechanics — verifying the traction applied during space closure and retraction, which typically works within the middle of this scale.
Recall force documentation — recording delivered force at each recall so that changes in elastic performance over time are documented rather than estimated.
Is the elastic force being measured or only estimated?
This instrument reads from 50 to 500 gf (cN), the span most routine intraoral elastic prescriptions fall into: engage either tip, extend to the working length and read the delivered force directly from the green scale.
