The W4000-500 is the higher-capacity sister to the W4000-100 in the Accuris W4000 Mini Balance family — same extraordinarily compact AAA-battery-powered portable balance form factor, with 500 g capacity × 0.1 g (100 mg) readability. Trade higher capacity (500 g vs 100 g) for lower readability (100 mg vs 10 mg) at slightly lower cost ($46 vs $52).
For complete chemistry rationale (mini balance tier vs compact / precision / analytical, application profile, AAA-battery portable design), see the W4000-100 parent page.

Pick the W4000-500 when:
- Workflow needs higher capacity (500 g vs 100 g) at portable form factor
- 100 mg readability is sufficient (10 mg precision not required)
- Lowest-cost balance procurement — $46 is the lowest-priced balance in the entire Accuris catalog
Pick the W4000-100 when: higher precision (10 mg) matters more than higher capacity.
Pick the W3300-500 compact when bench-top form factor + AC power matter (vs portable) and 10 mg precision is needed at 500 g capacity.
Application Profile
Lowest-cost portable balance procurement — labs needing the cheapest possible balance for individual-investigator workflows, field deployment, or educational programs benefit from the W4000-500 ($46).
Field-deployment bulk weighing — environmental, agricultural, veterinary field labs needing 500 g capacity in portable form factor.
Individual-investigator portable kits — researchers needing their own dedicated bulk-weighing balance for portable workflows.
Educational laboratory bulk weighing — undergraduate / graduate programs benefit from the lowest-cost balance for student-cohort exercises requiring 500 g capacity.
Backup / spare balance for higher-capacity workflows — labs maintaining a portable bulk-weighing spare alongside higher-precision bench balances.
Multi-cycler facility procurement — facilities benefiting from per-workstation bulk-weighing portable balance at low per-unit cost.
Frequently Asked Questions
Q: What capacity and readability does the W4000-500 have? A: 500 g capacity with 0.1 g (100 mg) readability.
Q: How is it different from the W4000-100? A: The W4000-100 offers higher precision (10 mg) at lower 100 g capacity for $52; the W4000-500 trades to 100 mg readability for 500 g capacity at $46.
Q: Is it really the lowest-cost balance in the catalog? A: Yes — at $46 the W4000-500 is the lowest-priced balance in the entire Accuris catalog.
Q: How is it powered? A: AAA batteries (included at first procurement), making it fully portable, with a backlit LCD and a snap-on protective cover for transport.
Ordering & Configuration
Battery inclusion. AAA batteries included at first procurement.
Calibration weights. The 100 mg readability supports calibration with standard M1 grade weights (W1005 family). Pair with W1005-500 (500 g M1 weight, $80) for full-range verification + W1000-TF tweezers ($42).
Confirm at quote: workflow portability needs, capacity (500 g vs 100 g sister), readability tier (100 mg vs 10 mg), calibration weight pairing, and lead time.
Warranty: Per Accuris standard warranty terms — confirm at quote.
Accuris W4000 Mini Balance family:
- W4000-100 — 100 g × 10 mg ($52)
- W4000-500 (this product) — 500 g × 100 mg ($46) — lowest-cost balance in catalog
Pick the W4000-500 for the lowest-cost portable balance with 500 g capacity; sister W4000-100 covers higher precision at smaller capacity; step to W3300 compact-balance family for bench-top procurement at the same readability classes.
