Pick the W1105-13-1000 set when:
- Standard balance is 1 kg capacity or larger
- Workflow needs full multi-point calibration coverage from low (1 g) through high (1 kg) mass values
- Sub-milligram calibration is NOT needed
Pairing with Larger Balances
For balances >1 kg capacity (e.g., W3200-5K 5 kg precision balance), pair the W1105-13-1000 set with individual W1005-2000 (2 kg M1 weight, $339.00) for full-range calibration coverage spanning low-mass through 5 kg.
Application Profile
See the W1105-8-50 parent page for the full application profile.
The 13-piece 1g-1kg set is the standard M1 calibration set for 1 kg+ standard / industrial balance facilities.
