Grundig Oxygen Concentrator Analysis Report

Overview and Device Identification

The visuals show a portable Grundig brand oxygen concentrator suitable for home and vehicle use. The device is designed to provide high-concentration oxygen to the user by separating nitrogen from ambient air. Accessories such as a power cable and a water humidification reservoir are also included with the product.

Brand and Model Identification

As a result of detailed visual inspection and verification, the brand of the device has been clearly identified as Grundig. The brand logo is clearly visible on the front surface of the device, on the upper control panel, and on the blue water reservoir. A quick online search indicates that a device with this design is associated with the model name BE04 or BE04A. However, since there is no direct inscription of a model number in the visuals, the report is limited to brand information only.

Usage and Functionality

This device is used to provide oxygen therapy to users who require respiratory support. The digital display and touch buttons on its upper panel allow for settings such as oxygen flow rate (O2 Flow), oxygen levels (O2 Levels), and operating time (Time Setting). Additionally, there is an SOS emergency button. Its portable design offers usability at home, in the car, or during travel.

Quantity Information

The visuals show the following total number of items:

• 1 Grundig Oxygen Concentrator
• 1 power cable and adapter
• 1 blue water humidification reservoir

Overall Condition

The device is in very good visual condition and can be described as “lightly used”. The expression “Cumulative Time: 00002 H” on its digital display indicates that the device has only been used for a total of 2 hours. This confirms that the product is almost new and does not have a long usage history. It generally has a clean and well-maintained appearance.

Physical and Mechanical Assessment

No cracks, breaks, or significant dents have been observed on the product’s white casing and black top panel. Minimal superficial scratches due to use might be present on glossy surfaces, but there is no prominent deformation in the photos. Mechanical components such as the water reservoir, buttons, and carrying strap appear intact and in place. The overall craftsmanship and logo quality of the device indicate it is an original product.

Electronic Components and Display Analysis

The device’s electronic system is in working condition. When powered on, the screen is observed to light up and display relevant data. The information on the screen is as follows:

• O2 LEVELS: %90
• O2 FLOW: 1 L (Liters/Minute)
• CUMULATIVE TIME: 00002 H (Total 2 hours of use)

This data indicates that the device operates with 90% oxygen concentration and a flow rate of 1 liter per minute. The touch control panel includes functions such as a voice alert, timer, flow setting, anion feature, and power buttons. All icons on the panel are clearly legible.

Accessories and Connections

The visual shows the power cable and adapter plugged into an outlet, which are necessary for the device to operate. The blue water reservoir, which humidifies the oxygen before delivery to the user, is also attached to the front of the device. No other connection sockets are visible on the device besides the oxygen outlet port and power input.

Potential Malfunction Risk

Based on visual evidence, no existing or potential malfunction risk has been detected in the device. The total usage time of only 2 hours, its clean and undamaged physical structure, and the apparent flawless operation of all its parts indicate reliability. The product’s condition is very high, and it is anticipated that it can be used without issues for a long period.
