GemRed 12" Digital Goniometer for Joint ROM Measurement (GR311 New Version)

GemRed 12-inch Digital Goniometer GR311: New Version for Joint ROM Tracking

The GemRed GR311 is a 12-inch digital goniometer designed to measure joint range of motion with a precise, easy-to-read display. Its compact form and tactile controls suit clinicians, trainers, and home users seeking consistent measurements without guesswork.

Built for daily use, the GR311 offers a modern interface and practical features that support clear data capture across sessions. The device guides you through setup, reading, and recording with minimal steps, while its durable construction keeps pace with busy clinics or busy homes.

What makes the GR311 edition different

• New color-coded buttons assign distinct functions for quick, memorable operation.
• Improved function allows a one-press zero reset, making it easier to measure different joints in sequence.
• Invert display feature lets you read degrees in awkward positions without repositioning the limb.
• Hold function freezes the reading so you can note results or transfer them elsewhere.
• Battery included (CR2032) ensures immediate use right out of the box.

How to use it in daily routines

Begin by aligning the goniometer with the joint landmarks you’re evaluating, then press the WHITE button to reset zero. The device then displays the measured range at a glance for quick documentation. In challenging positions, press the RED button to invert the readout for a comfortable view.

Use the HOLD function to lock a measurement momentarily, useful when comparing notes or compiling patient or client records. The included CR2032 battery means you can start working immediately, without searching for replacements.

Practical notes for real-world use

The GR311’s balanced size and reliable digital readout make it suitable for use in clinics, rehabilitation settings, or at home. The combination of legible digits, color-coded controls, and a straightforward workflow supports consistent data capture across sessions, helping you track progress over time without ambiguity.

• Clear digits enhance quick scanning during busy days.
• When you learn the controls, setup time is reduced.
