FAQ – Frequently Asked Questions about KERN Chair Scales

1. Where are KERN chair scales typically used – and when are they particularly useful?

Chair scales are used whenever patients cannot safely stand on a conventional scale – for example, due to limited mobility, balance issues, or fall risk.
They are ideal for use in hospitals, care homes, rehab centers, GP practices, and facilities for people with disabilities. Seated weighing eliminates the need for lifting or transferring, making it safer for patients and easier for staff.

2. What are the differences between the MCC, MCD, and MCN models – and which is best for my needs?

The three main series differ in terms of approval, features, and connectivity:

• MCC series: Battery/mains powered, Class III certified, mobile.
• MCD series: Affordable entry-level model, battery powered, up to 300 kg, not certified.
• MCN series: Medically approved, with digital interfaces – ideal for eHealth workflows.

The right model depends on your specific environment and documentation requirements.

3. Why is Class III medical approval important – and when do I need a certified chair scale?

Class III certification in accordance with EU Directive NAWI 2014/31/EU is legally required whenever a person’s weight is used for medical purposes. That includes diagnosis, treatment, progress monitoring, or official documentation within medical settings.
Typical use cases requiring certified chair scales:

• Hospitals and clinics – e.g., geriatrics, oncology, internal medicine
• Rehabilitation centers – for weight tracking in bariatrics or mobility disorders
• Medical practices – general medicine, gynecology, diabetology, etc.
• Care facilities with medical supervision – where documentation is required
• Public health institutions – e.g. screenings and preventive programs

Important: If the weight is used only internally or for organizational purposes (e.g., meal planning, basic monitoring), no medical certification is required. In that case, a model like the KERN MCD series is sufficient.
If you want to work in a legally compliant and medically accurate way, a Class III approved and optionally verified chair scale – like the KERN MCC or MCN – is essential.

4. How does the tare function work – and why is it important?

The tare function allows you to store the weight of the empty chair before weighing. This ensures the display shows only the net body weight of the patient – no manual subtraction required.
This is crucial for accurate clinical documentation, such as fluid balance, nutritional monitoring, or medication dosing.

5. Which models are suitable for digital data transfer – and what interfaces are available?

If you need to digitally document weight values or transfer them to a patient management system, the MCN series is ideal. These models offer modern interfaces such as USB, RS-232, Bluetooth, or Wi-Fi.
With KERN BalanceConnection software, data can be transferred directly to clinical or documentation systems – perfect for digitized healthcare workflows.

6. Can chair scales be used mobile within a facility – and what should I consider?

Yes – all KERN chair scales are equipped with transport wheels and can be moved flexibly within the facility. Models with rechargeable battery operation offer even more independence, enabling use directly in patient rooms without the need for a nearby power outlet.

7. Which patient groups can be weighed using a chair scale – and what is the maximum capacity?

Chair scales are ideal for people with reduced mobility, instability, severe fatigue, or obesity. Maximum capacity depends on the model:

• MCC & MCN: up to 250 kg
• MCD: up to 300 kg

This makes them suitable even for bariatric patients.

8. What advantages does a chair scale offer compared to a standard personal or platform scale?

Chair scales provide safe, comfortable, and seated weighing without requiring the patient to stand or transfer. Compared to platform scales, they offer:

• Integrated seating with backrest and armrests
• Footrests and stable frame
• Reduced physical strain on caregivers
• More safety and dignity for the patient

They are the preferred solution for patients with limited mobility or in long-term care.
