Scubapro Digital Magnehelic

A digital differential (Magnehelic) pressure gauge designed specifically for scuba regulator servicing. It accurately measures the inhalation/cracking effort (negative pressure) of a second-stage regulator, helping technicians tune regulators precisely and consistently 

Key Technical Specs

• Measurement Range: Typically ±55 inH₂O (inches of water), displayed with 0.01‑unit precision

• Selectable Units: Supports about 11 units (e.g., inH₂O, cmH₂O, Pa) to suit different calibration preferences 

• Display & Controls:

  • Digital LCD screen with a data‑hold function.

  • Auto power‑off feature to conserve battery 

• Power: Uses a standard 9 V battery (not always included due to shipping regulations) 

• Calibration Accuracy: Maintains high precision, usually within ±1 % full‑scale.

Included & Required Accessories

• Typical Inclusions: Gauge body, universal mouthpiece adapter, flexible hose, carrying pouch

• Additional Optional Items: Spare adapters (if not included), calibration equipment.

• Usage Tip: Some kits are sold without the adapter, so double-check before purchase 

Primary Use

• Measures the pressure needed to open (cracking) the valve of the 2nd-stage regulator.

• Helps ensure consistent breathing resistance, crucial for performance and comfort.

• Used during regulator servicing to validate or adjust set-up.

Why It’s Valuable

• Precision tuning: Offers objective measurement—no guesswork.

• Efficiency: Digital display and hold/save function speeds up setup.

• Durability: Rugged build suitable for workshop environments.
