Pressure Modules

External pressure modules for compatible Crystal and Additel calibrators — expand range coverage without buying a second handheld.

What a pressure module does

A pressure module is a remote sensor that plugs into a documenting calibrator or indicator. Swap modules to cover vacuum through high pressure while keeping one documenting platform.

When to use modules

• **Multi-range shops** — one calibrator body, several sensor ranges.
• **Intrinsically safe / special media** modules when the job demands them (check each SKU).
• **Bench automation** — modules often pair with controllers and documenting workflows.

Brands

Crystal and Additel external modules matched to their calibrator families. Confirm connector and firmware compatibility on the product page before ordering.

Calibration

Modules are measuring instruments and can usually ship with **ISO/IEC 17025 accredited calibration**. Ask for module-level certificates when your quality system requires them.
