Certeza CR-1002 Standard Type Aneroid Sphygmomanometer

The Certeza CR-1002 is a standard-type aneroid sphygmomanometer — a manual blood pressure measuring device used with an auscultatory technique (stethoscope listening to Korotkoff sounds) to determine systolic and diastolic blood pressure. Designed for reliability and durability, it is suitable for use by healthcare professionals, medical students, and trained home users.

The 52mm diameter manometer gauge is constructed from durable zinc alloy, with a measurement range of 0–300 mmHg and an accuracy of ±3 mmHg. A stop pin prevents over-inflation beyond the safe pressure limit. The chrome-plated brass air release valve with spring and standard end valve provides smooth, controlled deflation for accurate auscultation. The grey nylon cuff with an artery label assists with correct positioning, and the dual-tube PVC bladder ensures even pressure distribution across the arm. The cuff fits arm circumferences of 27–40 cm (bladder size 22 × 12 cm).

Why Choose Certeza Sphygmomanometer

• Zinc Alloy Manometer Gauge: Durable, accurate 52mm gauge with 0–300 mmHg range and ±3 mmHg accuracy.
• Stop Pin: Prevents over-inflation of the cuff beyond safe pressure limits.
• Chrome-Plated Brass Air Release Valve: Spring-loaded valve with standard end valve allows smooth, controlled deflation for accurate blood pressure auscultation.
• Nylon Cuff with Artery Label: Grey nylon cuff with printed artery marker for correct anatomical positioning.
• Dual-Tube PVC Bladder: Provides even, consistent pressure distribution across the arm during inflation.
• Cuff Fits 27–40 cm: Covers a standard adult arm circumference range.
• Bladder Size 22 × 12 cm: Standard adult bladder size.
• Storage Bag Included: Keeps all components organised and protected between uses.
• For Professional and Trained Home Use: Suitable for clinics, hospitals, and trained home users familiar with auscultatory BP measurement.

Usage Instructions

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

Warnings and Precautions

• This is a manual device requiring auscultatory technique — proper training is essential for accurate readings. Untrained users may obtain inaccurate measurements.
• Do not inflate the cuff beyond the stop pin — over-inflation can cause discomfort or injury.
• Ensure the cuff bladder is fully deflated before each measurement.
• Have the device calibrated periodically by a qualified technician to maintain accuracy.
• This device requires use with a stethoscope (not included).
