Certeza CR-1004 Large Dial Aneroid Sphygmomanometer

The Certeza CR-1004 is a large dial aneroid sphygmomanometer designed for use by healthcare professionals and trained users who benefit from an oversized, highly legible gauge. The 57×76mm milky white and deep blue manometer display — larger than the standard 52mm round gauge on the CR-1002 — provides significantly improved readability during auscultatory blood pressure measurement, particularly in clinical settings where the gauge may need to be read at a distance or angle.

The gauge body combines a durable zinc alloy back with an ABS plastic front, balancing robustness with weight efficiency. A stop pin prevents over-inflation beyond the safe pressure limit. The grey cotton cuff with an artery label assists correct anatomical positioning, and the dual-tube latex bladder provides consistent, even pressure across the arm. The chrome-plated brass air release valve with spring and standard end valve delivers smooth, controlled deflation. Cuff fits arm circumferences of 27–40 cm (bladder size 22×12 cm). Accuracy is ±3 mmHg across the 0–300 mmHg measurement range.

Why Choose Certeza Sphygmomanometer

• Large Dial (57×76 mm): Oversized milky white and deep blue display for superior readability during auscultatory measurement — easier to read than standard 52mm round gauges.
• Zinc Alloy and ABS Construction: Durable, robust gauge housing for clinical and professional use.
• Stop Pin: Prevents over-inflation beyond the safe pressure limit.
• Chrome-Plated Brass Air Release Valve: Spring-loaded valve with standard end valve for smooth, precise deflation control.
• Cotton Cuff with Artery Label: Comfortable cotton material with printed artery marker for correct anatomical positioning.
• Dual-Tube Latex Bladder: Provides even, consistent pressure distribution across the arm.
• ±3 mmHg Accuracy: Clinical-grade accuracy across the full 0–300 mmHg range.
• Cuff Fits 27–40 cm: Standard adult arm circumference range.
• Storage Bag Included: Keeps all components organised and protected between uses.

Usage Instructions

1. Have the patient rest for at least 5 minutes. Seat them with feet flat on the floor and the arm at heart level.
2. Wrap the cuff snugly around the upper left arm, 2–3 cm above the elbow. Align the artery label with the brachial artery.
3. Position the stethoscope diaphragm over the brachial artery, below the cuff edge.
4. Close the air release valve and inflate to approximately 30 mmHg above the expected systolic pressure.
5. Open the valve slowly (2–3 mmHg per second). Note the pressure when the first Korotkoff sound is heard — this is the systolic reading.
6. Continue deflating. Note the pressure when sounds disappear — this is the diastolic reading.
7. Release all remaining pressure. Record the readings.

Warnings and Precautions

• This is a manual auscultatory device — proper clinical training is required for accurate readings.
• Do not over-inflate beyond the stop pin pressure limit.
• Ensure the bladder is fully deflated before each new measurement.
• A stethoscope is required but not included.
• Have the device calibrated periodically by a qualified technician.
