ERKA Perfect Aneroid Blood Pressure Monitor Analysis Report

Device Identification

The product in the image is a manual blood pressure measuring device (aneroid sphygmomanometer) used for medical purposes. The device consists of a manometer (dial gauge), a bulb (air pump), a tube system, and a cuff worn on the arm. Additionally, in the upper part of the image, the metal earpiece and the beginning of the tube of a stethoscope, which is independent of the product but complementary in terms of use, are partially visible.

Brand and Model

A detailed examination of the device’s manometer dial clearly identified the red ERKA. logo and, immediately below it, the model name Perfect. At the bottom of the dial, the inscriptions “The Original” and “Made in Germany” are present. In light of this data, the product’s brand is ERKA, and its model is the Perfect aneroid sphygmomanometer. The product exhibits the characteristic color and material features of ERKA’s “Green Cuff” series.

Originality

Considering the clarity of the text characters on the dial, the proportion of the ERKA logo, the chrome plating quality of the manometer, the “Made in Germany” embossing on the bulb, and the regular stitching of the cuff, the product is assessed to be a 100% original ERKA product.

Areas of Use

This device is used in professional healthcare institutions (hospitals, clinics, family health centers) and at home to manually measure blood pressure. It is a mechanical device that performs precise measurements, widely preferred, especially in cardiology and internal medicine. Its use requires an operator familiar with the auscultation method and the support of a stethoscope.

Quantity Information

A total of 2 medical products/parts are present in the image:

• 1 ERKA Perfect Aneroid Sphygmomanometer (integrated system including cuff and manometer).
• 1 Stethoscope (Only the metal earpiece and the upper part of the tube are partially visible).

Label Information

The label and inscription information identified on the product is as follows:

• Cuff Label: “RANGE: 29-40 cm” (This information indicates that the cuff is suitable for users with an arm circumference between 29 cm and 40 cm). Additionally, a warning sign within a triangle and a red “CE” mark are present.
• Manometer Dial: Brand “ERKA.”, Model “Perfect”, Origin “Made in Germany”, Certification “CE 0124”.
• Bulb Inscription: The inscription “Made in Germany” is legible in embossed form on the rubber surface.
• Serial Number: A series of numbers starting with 200 is located in the middle of the dial (e.g., 20018606), but due to reflection and resolution, the complete number could not be definitively confirmed.

General Condition

According to visual inspection, the device is used but in a clean and well-preserved condition. Although second-hand, it gives the impression of being well-maintained or meticulously used. No significant dirt or signs of wear are visible.

Physical Deformations

No tears, rips, or significant color fading have been detected on the product’s green fabric cuff. The metal tensioning rods (hook mechanism) on the cuff appear shiny and show no signs of rust or oxidation. No rubber-specific cracks or deep fissures are visible on the bulb.

Mechanical and Electronic Components

The product operates entirely on mechanical (analog) principles; it has no electronic components.

• Manometer: The chrome-plated body is clean. The gauge glass is intact. The needle is close to the “0” point, but the exact calibration status can only be determined during use.
• Tubes: In the dual-tube system, no visible crushing, breakage, or deformation due to drying is present.
• Valve: The metal air release valve (screw) at the tip of the bulb is in place, and its physical integrity is complete.

Size and Compatibility

The “RANGE: 29-40 cm” inscription on the cuff indicates that the product is of Adult (Large) size. It is also suitable for arms slightly wider than standard adult arms. Thanks to its hooked (clasp) cuff structure, it can be quickly and practically secured to the arm.

Accessories

The device’s original storage bag (zippered case) is not present in the image. The gray-tubed stethoscope located in the upper part of the image is not an included part of the device but a complementary external accessory, and only its earpiece part is visible.

Existing Defects and Risks

No concrete defect that could hinder the product’s operation (such as a broken or burst tube, or missing parts) has been detected in the images. The product’s condition suggests it is ready for use. However, due to it being a precision measuring device, the calibration check of the manometer cannot be performed visually.
