Hydrometers are typically calibrated annually or whenever accuracy is critical—for example, if used for regulated testing or research purposes. If used less frequently or in less critical roles, calibration intervals may be extended according to lab policy or manufacturer recommendations.

Quick Overview
- What it is: A laboratory hydrometer for measuring specific gravity of liquids.
- Typical use: Used in science labs, industry, and research for quick, direct measurement of liquid density.
- Status: Discontinued (out of production, but may be available from surplus or second-hand suppliers).
A Fisher Scientific 11-556FC Hydrometer doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 11-556FC, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
