Marsden M-550 Digital GP Floor Scale, Class III Approved, Accurate, Lightweight, with Optional Bluetooth
- Class III and MDR Approved, 160kg capacity (200kg with Bluetooth), 200g precision below 100kg, meeting NAWI Directive requirements for GP surgery diagnosis and monitoring as the most cost-effective Class III-approved floor scale in the Marsden range.
- Larger-than-average platform and clear digital display improve usability for frail and elderly patients stepping on, with Hold and Tare functions and BMI calculation supporting routine GP clinical assessments and medication review workflows.
- Up to 100 hours from 4xAA batteries, eliminating mains dependency in GP rooms without power point access, with tap-on activation and straightforward five-button operation requiring no specialist clinical training.
- Optional Bluetooth connectivity increases capacity to 200kg and enables direct NHS telehealth data transfer, supporting GP-led remote weight monitoring programmes and chronic disease management in primary care settings.
Marsden M-550: Class III and MDR Approved Entry-Level GP Floor Scale with Optional Bluetooth
The Marsden M-550 is the most affordable Class III and MDR Approved floor scale in the Marsden medical range, designed specifically for GP surgeries, pharmacies and primary care settings where daily adult patient weighing is a routine clinical requirement but budget constraints favour a cost-efficient solution over premium connectivity. With 160kg standard capacity (expanding to 200kg with the Bluetooth option), BMI calculation and Hold function, the M-550 covers the core clinical functions required for general adult monitoring, medication review and chronic disease management in primary care.
The larger-than-average platform and clear digital display specifically address GP surgery requirements where frail and elderly patients need confidence and stability when stepping onto the scale during routine consultations.

Regulatory and Clinical Compliance
Class III and MDR approval confirm the M-550 meets NAWI Directive precision standards and EU Medical Device Regulation requirements for clinical use in GP surgery and primary care settings. MDR (Medical Device Regulation) is the successor to MDD, providing updated regulatory assurance for clinical devices. The 160kg standard capacity covers the majority of adult patients presenting in standard GP surgery consultations, and the Bluetooth-enabled 200kg variant extends coverage to a wider range of patients while simultaneously enabling telehealth data transfer for NHS chronic disease monitoring programmes including NICE hypertension (NG136) and Type 2 diabetes (NG28) weight monitoring recommendations.
Frequently Asked Questions
Why does the M-550 have a higher capacity with Bluetooth than without it?
The 200kg capacity of the Bluetooth-equipped M-550 is a result of the hardware configuration used to support wireless connectivity in this model, which uses a different internal weighing module to the standard 160kg variant. The Bluetooth module is not added onto the 160kg base scale but requires a separate build configuration that happens to deliver a higher weight range. In practice, this means that practices selecting the Bluetooth version for telehealth purposes also benefit from the higher capacity as a consequence, without paying a separate premium for extended range.
Is the M-550 a suitable replacement for a mechanical dial scale in a GP surgery?
Yes, and the replacement represents a meaningful clinical upgrade. The M-550 provides five times the readability precision compared with standard 1kg mechanical dial scales at 200g graduation, eliminates parallax reading errors from analogue displays, and adds BMI calculation as a standard function. Class III approval confirms it meets the NAWI Directive standard required for clinical diagnosis and treatment, while mechanical dial scales do not carry this certification and cannot be used for clinical diagnostic purposes under the Directive's requirements.
