The Ohaus SJX622M Trade Approved Balance is a professional full-size table balance designed specifically for accurate weighing in jewellery and precious metal applications.
Approved by Trading Standards for use in trade, the SJX622M can be used when buying precious metals by weight, giving jewellers, gold buyers and professionals confidence when handling valuable materials. Unlike older approved balances that may have restrictions on where they can be used, this model can be transported and used anywhere.
The SJX622M offers a 620g capacity with different resolution options depending on the application:
- For your own information: 620g / 0.001g readability
- For trade use when buying precious metals: 620g / 0.1g readability (the balance displays finer increments, but the final decimal place should be ignored for approved trade weighing)
Compact, lightweight and sturdy, this balance is ideal for workshop, shop counter or mobile use. It operates from mains power or standard AA batteries, making it convenient for use wherever accurate weighing is required. A built-in calibration weight allows easy calibration without needing to carry additional equipment.
Advanced weighing functions
The Ohaus SJX622M includes a range of useful professional functions:
Parts Counting
Quickly count identical small components. Simply weigh a known quantity (such as 20, 50 or 100 pieces), then add more items and the balance will display the number of pieces rather than the weight.
Percentage Weighing
Compare items against a reference sample. Once the sample has been set, the balance shows whether each item is heavier or lighter as a percentage.
Check Weighing
Set upper and lower weight limits and quickly identify whether items fall within tolerance. The display indicates whether the weight is below, above or within the selected range.
Totalising
Add multiple items together while displaying both the individual addition and the combined total weight.
Customisable Modes
The MODE function allows you to select which features are available, keeping operation simple by hiding functions you do not use.
