Description
The ADC Goniometer 12 Inch spans larger joints with a 12-inch arm and reads them on a 360-degree head carrying three calibrated scales in 1-degree increments. It is built for knees, shoulders, elbows, and hips, where a short goniometer arm cannot align with the limb honestly.
- Three calibrated scales – The fullest scale set in the line reads in 1-degree increments for precise range-of-motion charting.
- 12-inch reach – Longer arms align to the anatomical landmarks of large joints for truer angles.
- Holds its reading – The arm remains in the measurement position until reset, preserving the angle for documentation.
- Latex and phthalate free – Made without phthalates or natural rubber latex.
Long-Arm Measurement for Large Joints
This 12-inch goniometer extends ADC's multi-use design to the joints where arm length decides accuracy: knees, shoulders, elbows, and hips. Its 360-degree head carries three calibrated scales, giving the clinician the right reference for flexion, extension, and rotation measurements. All scales read in 1-degree increments, fine enough to document the small gains rehabilitation actually produces. The arm holds its measured position until reset and carries a linear scale in inches and centimeters for length work. Orthopedic clinics, rehabilitation hospitals, and sports medicine practices get a single instrument for their largest measurement tasks.
Features and Benefits
Measurement Head
- 360-degree rotation – The full-circle head measures any joint without a dead zone.
- Three calibrated scales – Three references cover the measurement conventions large-joint work demands, each in 1-degree increments.
Arm and Build
- 12-inch arm – The longer arm aligns with distant anatomical landmarks on large limbs.
- Position-holding design – The arm remains in the measurement position until manually reset.
- Linear scale – Inch and centimeter markings run along the arm.

Why Choose This Goniometer
Large-joint goniometry with a short instrument invites parallax and landmark guessing, and the errors land in the chart as fact. A 12-inch arm and three calibrated scales are the professional answer, holding a one-degree reading steady while it is verified. For orthopedic and rehab documentation, that integrity is the product.
- Landmark-true alignment – The long arm reaches the reference points large joints require.
- Three-scale versatility – More references on one head means fewer instrument swaps per evaluation.
- One-degree resolution – Fine increments document incremental rehab gains honestly.
- One-year backing – Coverage runs one year for the original purchaser.
Frequently Asked Questions
When is the 12-inch size the right choice?
Choose it for large joints such as knees, shoulders, elbows, and hips, where longer arms align to the landmarks accurately. The 8-inch version, listed separately, suits smaller joints and pockets.
What do the three scales add?
Three calibrated scales give the clinician the appropriate reference for different measurement conventions without changing instruments. All read in 1-degree increments across the 360-degree head.
Does the arm hold the reading?
Yes, the arm remains in the measurement position until it is reset. The angle can be verified and charted after the patient relaxes.
Can it measure length too?
Yes, a linear scale in inches and centimeters runs along the arm. It handles quick limb-length and related measurements in the same session.
What warranty applies?
ADC provides a one-year warranty for the original retail purchaser. Coverage is measured from delivery to the original retail purchaser.
