【High Precision & Wide Range】：Accurately measures tension from 7 to 50 N/cm with a tolerance of ±5%, ideal for both ultra-fine high-strength screens and standard mesh. Supports radial and weft tension testing to ensure uniform tension across the entire screen surface, critical for high-quality printing results. 【Mechanical & Battery-Free Design】：Pure mechanical transmission without the need for batteries or external power. Features a clear pointer dial for intuitive reading; note that the first full rotation of the pointer is for zeroing, and valid readings start from the second rotation for accurate data. 【Pre-Calibrated & Easy to Use】：Factory-calibrated zero position for immediate use, no additional adjustment required. Comes with a standard calibration glass for quick zeroing checks. Simply place the gauge on the screen, lightly tap the mesh, and read the value—suitable for both professional workshops and DIY screen printing. 【Widely Applicable】：Perfect for various screen printing scenarios, including PCB circuit board manufacturing, multi-color overprinting, textile printing, advertising signage, and metal etching. Works with polyester mesh, stainless steel mesh, and other common screen materials. 【Durable & Compact】：Sturdy construction with shock absorption to resist damage from accidental drops. Compact size (108×76×44mm, net weight 500g) for easy storage and portability.
