Linen Testers are Folding Magnifiers used for inspecting fabric weaves, and other surfaces. They are widely used for inspection & quality control of  textiles, ballistic fabrics, bar code width, printing registration, or any visual surface examination. With their specialized measurement capabilities and and portability Linen Testers can be the ideal magnifying tool for evaluating fabrics, making precision measurements, inspecting printed material. Linen Testers are a fixed focus stand design that was originally developed to inspect, count fabric quality and thread count The industry standard magnification for a linen tester is 5x however higher magnification maybe necessary for some inspection. Linen Testers are the go magnifier that folds to fit in the pocket for counting and inspecting the thread counts, fabrics and textiles./p>

• Textile Thread Counts and Inspection: Linen tester magnifiers are used for inspecting &  counting textile thread counts, bar code density, printing registration,  and inspections of other flat surfaces. The engineered base and measuring scales bring clarity to the smallest elements of fabrics and materials.
• Line Scales & Glass Reticles for Fabric Evaluation: Linen testers come equipped with line scales in MM or Inch scales & also with glass reticles that enhance the evaluation of fabrics. These aid in assessing thread counts, print quality, and other intricate fabric and surface attributes.
• Printing Industry Applications: Beyond textiles, linen testers are used in the printing industry for tasks such as checking color separation, registration, bar code line spacing and quiet zones, as well as other fine visual details in printed materials.
• Selecting Magnification Range: Our Linen tester selections come in magnification range of 4x to 10x. The industry standard typically falls within the 5x to 6x range, offering a balanced view of fine details without sacrificing optical clarity.
• Inverse Relationship Between Lens Size and Power:  Please always note: the inverse relationship between lens size and magnification power. As Magnification goes up lens size goes down due to laws of physics. This principle guides the design of linen testers to ensure that magnification remains balanced and effective.
