ERKA Perfect Aneroid Blood Pressure Monitor and Stethoscope Set Analysis Report

Device Identification

The examined images show a manual blood pressure measuring device (sphygmomanometer) and a stethoscope, which together constitute a medical diagnostic set. The product set consists of a cuff, a pump (bulb), a manometer (dial), a double-tube system, and a carrying case. This product is a professional medical equipment used by healthcare professionals to manually measure blood pressure and to listen to heart/lung sounds via the stethoscope.

Brand and Model

As a result of detailed examinations of the product in the images, brand and model information has been definitively identified:

• Brand: Based on the cuff label, the embossed text on the pump (bulb), and the print on the manometer dial, the brand has been determined to be ERKA.
• Model: Based on the gold-gilded print on the green carrying case and the text inside the manometer dial, the model has been identified as Perfect Aneroid.
• Origin: The labels on the product clearly show the inscription “Made in Germany” and the company’s location, “Bad Tölz”.

Authenticity

Considering the quality of the logo’s craftsmanship, the fine details on the manometer dial (serial number, CE markings, origin information), the chrome plating quality on the metal components, and the special model print on the case, the product is evaluated to be an original ERKA production. The location information “Bad Tölz D-83646” and serial number tracking, which are not seen in counterfeit or aftermarket products, are factors supporting its authenticity.

Areas of Use

This device set is designed for use by healthcare professionals such as doctors, nurses, paramedics, and medical students in hospitals, clinics, and home healthcare services. Its “Aneroid” type indicates that it operates without mercury, and the inclusion of a stethoscope shows its suitability for blood pressure measurement using the auscultation (listening) method and general examination.

Quantity Information

The total number of parts shown in the images is as follows:

• 1 integrated body with manometer and pump (bulb).
• 1 green, double-tubed fabric cuff.
• 1 stethoscope.
• 1 green carrying case with “Perfect-Aneroid” inscription.

General Condition

The device is generally in a clean and well-preserved condition. Although it is a used product, it does not show significant visual signs of wear and tear. Metal parts retain their shine, and fabric components appear clean. The overall appearance of the device indicates careful use and good storage.

Physical Deformations

No noticeable cracks, breaks, rust, or severe dents have been detected on the product’s casing, manometer glass, or metal connection points. No tears or unraveling are visible in the cuff fabric. Only a slight discoloration (yellowing) that may occur over time on the earpieces (ear tips) of the stethoscope might be observed, but this is not a functional deformation.

Mechanical Components

The manometer’s needle (dial pointer) rests steadily at the “0” mark. This is the most important indicator that the device’s calibration is visually sound. No mechanical damage is visible on the cuff connection screws or hose inlets. No cracks or signs of drying have been found in the rubber structure of the bulb (pump).

Accessories

The set is shown with its original zippered carrying case. The zipper and stitching on the case appear to be in good condition. The stethoscope is present as part of the set. The metal screw-in sockets that connect the cuff hoses to the device body are complete and present.

Label Information

The technical data read on the manometer dial and cuff label are as follows:

• Brand: ERKA.
• Serial Number: 1103462
• Model Series: Perfect Aneroid
• Location Code: D-83646 Bad Tölz
• Certificate: CE 0124
• Origin: Made in Germany

Display (Dial) Analysis

The manometer dial is analog and displays pressure values between 0 and 300 mmHg. The scaling is clear and legible. The needle rests precisely at the zero point when no pressure is applied, indicating that the device maintains its sensitivity. The dial glass is clean and scratch-free.

Size and Compatibility

The cuff size is estimated from the visual as “Standard Adult” size (Green color in the ERKA product range is typically used for adult-sized cuffs). The product’s hose connections are a double-outlet screw system, so this feature should be noted when sourcing spare parts.

Documents

No invoice, warranty certificate, or user manual for the device is present in the images. Therefore, information regarding whether its warranty is still active cannot be provided based on the visuals.

Current Malfunction

No distinct malfunction, such as a broken part, severed hose, or shattered glass, that would prevent the device from operating has been detected in the images.

Potential Malfunction Risk

The device’s condition appears very good. Only rubber/plastic-based materials such as the stethoscope’s tubing and cuff hoses might harden over time. However, based on the current images, these parts appear flexible, and no cracks are visible, so no short-term risk is anticipated. The stethoscope eartips might be desired for replacement for hygienic reasons.
