The Morelli Force Gauge Dynamometer — 100 to 1600 gf (cN) is a mechanical tensiometer that reads traction from 100 to 1600 gf (cN) on a single direct-reading scale. It is the instrument to reach for when the force being verified is generated by extraoral traction or by full-strength interarch elastics. It is built with a stainless steel body and polymer tips and carries a red scale for immediate identification on the tray.
Key Features
100 to 1600 gf (cN) measuring range — a single scale covering moderate through heavy orthodontic loads.
Two tips for easy positioning allow the gauge to be hooked and read from either side of the arch, so extraoral and intraoral attachments can be reached without repositioning the patient.
Purely mechanical operation requires no batteries, calibration cycle or electronics — the reading is taken directly from the scale at chairside.
Red scale color marks this instrument as the heavy-force gauge for quick identification on the tray.
Corrosion-resistant construction in stainless steel with polymer tips, for routine reprocessing between patients.

Clinical Applications
Extraoral traction checks — verifying the traction delivered by a facebow or headgear assembly before it is handed to the patient, a load that sits in the upper portion of this scale.
Full-strength interarch elastics — confirming the force of Class II and Class III elastics prescribed at full strength.
Heavy-force appliance verification — documenting the actual force delivered by heavy elastics and traction assemblies at each recall, so prescription and delivery can be compared.
Are your heaviest mechanics delivering the prescribed force?
This instrument reads from 100 to 1600 gf (cN), the span occupied by extraoral traction and full-strength interarch elastics: engage either tip, pull to the working position and read the value directly from the red scale at chairside.
