Precision Jewelry Scale Retoo E702 — LCD, 100 g capacity, 0.01 g readability

Retoo E702 is a precision jewelry scale with an LCD display, 100 g maximum capacity and 0.01 g readability. It is intended for weighing gemstones, precious metals, small components and other light items where high resolution and repeatability are required. The compact form factor and clear readout make it suitable for use in workshops, retail environments and at home for appraisal, dosing or inventory tasks.

Advantages

The scale provides 0.01 g resolution across its 100 g range, enabling precise measurement of small items. The LCD display offers clear numeric feedback and the tare function allows for net weight determination of items inside containers. Built-in unit conversion simplifies switching between grams, ounces and other common units, while a stable measurement algorithm reduces fluctuations from minor disturbances.

Suitable for

• Weighing gemstones and cut stones
• Measuring precious metal samples (gold, silver, platinum) for valuation
• Weighing small jewelry components, findings and beads
• Laboratory samples, hobby electronics components and small parts
• Home use for precise recipes, supplements or craft materials

When it may not be suitable

This scale is designed for small, lightweight items up to 100 g and is not suitable for bulk items or objects exceeding its maximum capacity. It is not intended for use as a high-capacity industrial scale or for weighing materials requiring trace-analytical laboratory accuracy beyond 0.01 g readability.

Key specifications

• Maximum capacity: 100 g
• Readability (graduation): 0.01 g
• Display: LCD numeric readout
• Functions: tare, unit conversion, stable-measurement mode
• Suitable measurement items: gemstones, precious metals, small components
• Form factor: compact tabletop design suitable for benchtop or portable use

How to use

Place the scale on a level, vibration-free surface and switch it on. Allow the display to stabilize before placing any item on the pan. Use the tare function to zero the scale when measuring items inside a container. Select the required unit with the unit button if conversion is needed. For best accuracy, avoid drafts, direct sunlight and heavy vibrations during measurement and calibrate the scale periodically according to the manufacturer’s instructions.

What to consider before purchase

• Maximum weight requirement: confirm that 100 g capacity meets your typical item weights
• Required resolution: 0.01 g readability is suitable for many jewelry and small-part tasks but not for microgram-level needs
• Usage environment: stable, draft-free surface improves accuracy; consider a calibration weight for verification
• Portability vs. workspace: compact size favors portability but provides a limited weighing area

Usage recommendations

For consistent results, allow the scale to warm up on a stable surface before use, use the tare function for containers, and perform occasional calibration checks with a known weight. Store the scale in its protective case or a dust-free area when not in use to preserve accuracy and extend service life.
