Jewellery scale BLOW JS13 (model 44-109#) precision balance for small items

The BLOW JS13 jewellery scale (model 44-109#) is a compact precision balance designed for accurate mass measurement of small items such as jewellery, gemstones and coins. Its small footprint and straightforward controls make it suitable for retail counters, appraisal work and hobbyist use where repeatable, reliable readings are required. The scale provides precision suitable for tasks that demand careful measurement of weight in grams and fractions of grams.

Advantages

The scale offers a compact design that fits easily on workbenches or in retail displays, combined with a weighing platform sized for small items. Its precision sensor delivers consistent readings with minimal drift, and the unit’s simple interface reduces setup time. The device is portable and consumes little power, making it practical for both stationary and mobile use.

Suitable for

• Weighing jewellery pieces such as rings, necklaces and earrings
• Measuring loose gemstones and small mineral specimens
• Counting and checking the weight of coins and small collectibles
• Retail and pawnshop item appraisal and pricing
• Hobbyist uses where fine mass measurement is required

Key specifications

• Compact form factor with small weighing platform suitable for tiny objects
• High-precision sensor capable of measuring small mass increments
• Measurement units commonly used for small items (grams and sub-gram resolution)
• Clear display and simple control layout for straightforward operation
• Low power consumption and portable design for mobile or counter use

How to use

Place the scale on a stable, level surface and ensure it is free from drafts and vibrations. Power up the unit, allow it to stabilise, and tare the platform if using a container. Gently place the item to be weighed in the centre of the platform and wait for the reading to stabilise before recording the mass. For best accuracy, handle items with clean tweezers or gloves to avoid adding residue or fingerprints that could affect results.

Usage recommendations

For reliable measurements, calibrate the scale periodically according to the manufacturer’s instructions and perform weighing in a controlled environment—away from direct airflow, extreme temperatures and magnetic sources. Use consistent placement on the platform and avoid overloading beyond the scale’s capacity.
