Goniometer price

Selecting the correct material is vital for accuracy and durability. For medical and physical therapy use, transparent plastic (PVC or Acrylic) goniometers are standard as they allow a clear view of the joint's axis of motion. For industrial or carpentry applications, stainless steel versions are preferred for their resistance to wear and precision-etched scales. Ensure the material is BPA-free and non-toxic if used in clinical settings.

Price is primarily driven by measurement precision and scale clarity. Look for units with dual scales (inches and centimeters) and a full 360-degree coverage. High-quality models feature ISOM (International Standard of Measurement) markings that do not fade over time. For digital versions, check the LCD resolution (typically 0.05°) and IP54 water/dust resistance ratings, which significantly affect the cost.

If the goniometer is intended for medical use, it must comply with FDA registration (Class I) in the US or CE Marking (MDR) in Europe. Ensure the manufacturer follows ISO 13485 quality management systems for medical devices. For electronic models, RoHS and FCC certifications are necessary to ensure electromagnetic compatibility and environmental safety.

The arm length is a critical factor; 6-inch arms are ideal for small joints (fingers/wrists), while 12-inch arms are required for large joints (hips/knees). Features like a locking nut to hold the angle measurement and calibrated friction joints that move smoothly but stay in place are essential for professional-grade accuracy.

The main risks include measurement inaccuracy due to poor calibration and material brittleness during transit. To mitigate this, always request a pre-shipment inspection (PSI) and verify that the supplier uses reinforced packaging to prevent the plastic arms from snapping or scratching.

Leverage volume by requesting tiered pricing structures; typically, orders exceeding 500 units can see a 15-25% price reduction. Discuss OEM/Private Labeling early, as custom branding usually requires a higher MOQ but adds significant retail value. On Made-in-China.com, look for 'Diamond' or 'Gold' audited suppliers to ensure negotiation stability.

Since goniometers are lightweight, air freight or international courier (DHL/FedEx) is often more cost-effective for small to medium batches. For large industrial orders, FOB (Free On Board) terms are recommended to maintain control over shipping costs. Ensure the HS Code (typically 9017.30 or 9018.90) is correctly declared to avoid customs delays.

Utilize Secured Payment services provided by reputable platforms like Made-in-China.com to protect your funds until delivery is confirmed. Always request a functional sample before placing a bulk order to test the tension of the pivot point and the legibility of the printed increments.
