Wholesale Waterproof 50kg/100lb Digital Fish Weight Scale with Length Measuring and LCD Display

A digital fish weight scale is an electronic hanging or portable scale built specifically for anglers, fishing brands and distributors. It uses a load‑cell or sensor to measure the weight of a catch, and shows the result on an LCD display.

These scales often support multiple units (kg, lb, oz), may include extra features such as tape measures or locking functions, and are built to resist moisture and outdoor conditions. They help users quickly and accurately record fish weight for sport, commercial or regulatory needs.

Our digital fish weight scale model is a premium digital fish weight scale designed for the market. It delivers a 50 kg (110 lb) load capacity with 10 g accuracy. The unit features an LCD display, water‑resistant housing, and an integrated 150 cm tape measure for length measurement.

A wide, non‑slip handle and a large hook facilitate easy attachment of the catch. The handle can swing for optimal weighing position and both handle and hook fold for compact storage. Power is provided by a built‑in rechargeable lithium battery, and as backup by 3× AAA batteries.

The scale supports unit conversion among KG, LB, JIN and OZ and displays ambient temperature. We welcome OEM and ODM orders, with customized packaging. As a digital fish scale trusted manufacturer in China, we supply global distributors and fishing‑gear brands with reliable, ready‑to‑brand solutions.

50kg Digital Fish Weight Scale Manufacturing Process

Design & Prototyping

We create detailed 3D models for the scale’s housing, LCD, hook, and handle using design Software. Prototypes are tested for fit and durability before moving to production.

Material Sourcing

The housing is made from high-strength ABS for durability, while stainless steel is used for the hook and karabiner to resist corrosion. We source load cells and microcontrollers from trusted suppliers.

Injection Molding & Metal Forming

Plastic parts are produced using precision injection molding machines. The stainless steel hook and karabiner are stamped and shaped using CNC machining and hydraulic presses for precise dimensions.

PCB Assembly

Our PCB assembly uses SMT machines for precise component placement and reflow soldering for secure connections. We perform electrical testing to ensure all components function correctly.

Final Assembly

The load cell, PCB, and LCD are installed into the housing, and the hook and karabiner are securely attached using industrial screwing and riveting machines. All wiring is insulated to prevent short circuits.

Calibration & Software Integration

We calibrate the scale using precision calibration equipment. The microcontroller is programmed for functions like tare, unit conversion, and auto-off, then tested to ensure full functionality.

Quality Control & Testing

Each unit undergoes visual inspection, load testing up to 300kg, and environmental testing for temperature and humidity resistance. We use a tensile testing machine to verify the accuracy and durability of the scale.

Potting & Encapsulation

Sensitive electronic components are potted using conformal coating material, ensuring moisture and corrosion protection. This is cured under controlled conditions.

Packaging & Labeling

The scales are packed securely in bubble wrap and custom boxes. Labels with product information, safety instructions, and OEM branding options are applied.

Shipping & Distribution

Finished products are organized for efficient shipping with tracking provided to customers.
