10X Three-Folding Tester Magnifier LED Illuminated

Quick Introduction: Stop guessing and start measuring. The 10X Three-Folding Magnifier (often called a "Linen Tester") is a timeless tool used by professionals to verify quality. Unlike handheld magnifiers that shake and lose focus, this unit unfolds into a rigid stand that sits directly on your subject. This creates a fixed, stable viewing distance while the built-in base scale allows you to measure thread counts, font sizes, or line widths with ease.

Detailed Specifications

• Magnification Power: 10X (Fixed Focus).

• Lens Diameter: 28mm (Large viewing area).

• Lens Material: Optical Glass (Distortion-free).

• Body Material: Heavy-duty Zinc Alloy (Black paint finish).

• Design: Three-folding "U" shape (Protects lens when closed).

• Base Scale: Dual measurement (Inch and millimetre markings).

• Dimensions (Folded): Compact ~50mm x 37mm x 12mm.

• Weight: ~100g (Solid metal feel).

Quality Advantage & Differentiation: Why choose this Zinc Alloy model?

1. Hands-Free Stability: The self-standing design eliminates hand tremors. You simply place it over the object and look down, leaving your hands free to manipulate the item or take notes.

2. Built-in Measurement: The base frame isn't just a stand; it's a ruler. The laser-etched scale allows for precise sizing of objects right under the lens without needing a separate calliper.

3. Durability: Made from solid metal (Zinc Alloy), this tool survives drops and crushing forces in toolboxes that would crack plastic loupes.

Key Applications & Usage

• Textiles & Fabrics: Originally designed to count the number of threads per inch (Thread Count) in linen and cotton.

• Printing & Graphics: Check CMYK dot registration (halftone dots) and verify font sharpness on proofs.

• Stamp & Coin Collecting: Measure the centring of a stamp or the size of a mint mark on a coin.

• PCB Inspection: Check trace widths and gap sizes on circuit boards.

What's Included & Required

• Included: 1x 10X Metal Folding Magnifier, 1x Storage Pouch (Synthetic Leather).

• Required: Ambient light (This model is passive; it uses room light or sunlight).

The "Virtual Technician" Support Panel

• ⚠️ HOW TO USE (Fixed Focus):

  • Do NOT hold this up to your eye like a telescope.

  • Correct Usage: Unfold the stand completely. Place the square base flat against the object you want to view. Look through the lens from a comfortable distance (about 5-10cm away). The stand is calibrated to set the perfect focal length automatically.

• ⚠️ LIGHTING TIP:

  • Since this unit has no LEDs, the "U" shape stand is open on the sides to let ambient light in. If the image is dark, rotate the stand so the open sides face your light source (window or lamp).

• ⚠️ STIFF JOINTS:

  • New units may be stiff. This is intentional to keep the stand upright. Do not lubricate the hinges, as oil can migrate to the glass lens. They will loosen slightly with use but remain firm.
