Portable Mechanical Spring Scale with Stainless Steel Hook for Fishing and Luggage Weighing

A mechanical spring scale offers a simple and dependable way to weigh fish, luggage, bait, and other items without batteries or electronic components. Its straightforward design makes it a popular choice for anglers, travelers, and outdoor users who need quick weight measurements in any environment.

This portable hanging scale is commonly used for boat fishing, shore fishing, camping, and travel. The built-in weighing hook allows users to check the weight of fish, bags, or equipment in seconds, while the integrated tape measure helps record fish length or item dimensions when needed.

Unlike digital scales that rely on batteries and electronic sensors, a mechanical spring scale continues to operate in wet, cold, or remote conditions. This makes it especially useful for fishing trips and outdoor activities where reliability is more important than advanced functions.

Designed for everyday carrying, the scale fits easily into a tackle box, backpack, or travel bag. Multiple capacity options are available to suit different weighing requirements, from small freshwater catches to larger saltwater fish and travel luggage.

Applications of Portable Mechanical Spring Scale

Widely used in family weighing, luggage weighing, vegetable weighing, fish weighing, animal weighing and other general weighing applications.

Product Specifications

Mechanical Spring Scale Product Details

Comfortable Handle with Finger Position

The handle features a finger-position design that provides a secure and comfortable grip during weighing.

Easy-to-Read Dual Scale Markings

Clear graduations in both kilograms and pounds make weight readings quick and easy to understand.

Built-In Tape Measure

The tape measure is conveniently stored inside the scale body and can be pulled out when measuring fish, luggage, or other items.

Practical Weighing Hook

The scale is equipped with a hanging hook for simple weighing of fish, bags, and other objects.

Quality Control of Mechanical Spring Scale

RTI implements strict quality control to ensure measurement accuracy, mechanical stability, and long service life of each mechanical spring scale.

Material Inspection

Stainless steel hooks and springs are tested for corrosion resistance and dimensional accuracy before production. All metal components meet SUS304-grade stainless steel standard or equivalent for outdoor and marine use.

Calibration Accuracy

Each scale is calibrated using certified standard weights across full load range (7kg, 11kg, 22kg). Measurement deviation is controlled within ±2% tolerance. Both kg and lb markings are checked for alignment and consistency.

Load Performance Testing

Each unit is tested under 110% rated load to verify spring stability and structural safety. No permanent deformation or scale shift is allowed after repeated loading cycles.

Mechanical Durability Test

Spring mechanism is tested for over 5,000 continuous load-release cycles. The scale must maintain consistent return position and stable reading accuracy throughout testing.

Assembly Control

Hook alignment, spring positioning, and internal movement clearance are inspected during assembly to ensure smooth operation and stable load transmission.

Final Inspection

Each unit undergoes 100% inspection before shipment:

• Weight accuracy check.
• Hook load test.
• Tape measure extension/retraction test.
• Visual inspection for defects.
• Functional operation test.
