Description

The Marsden M-400 is a Class III Approved portable baby and toddler scale. Ideal for midwives, health visitors, and paediatric clinics

The Marsden M-400 is a versatile, high-precision weighing solution designed specifically for the rigours of community midwifery, health visiting, and paediatric wards. Combining clinical-grade accuracy with a lightweight, 4kg portable chassis, the M-400 is the primary choice for healthcare professionals who require a reliable “all-in-one” scale for infants and toddlers.

As a Class III and MDD Approved medical device, the M-400 meets all legal requirements for medical monitoring and diagnosis. Its unique slide-off pan design ensures a seamless transition from a secure baby scale to a stable floor scale for toddlers, providing exceptional value and longevity for any clinic.

Designed for Community & Clinical Excellence

The M-400 is engineered to handle the challenges of mobile healthcare without compromising on medical precision.

Key Performance Features:

  • Dual-Purpose 2-in-1 Design: The hygienic, ergonomic baby pan can be quickly removed to reveal a low-profile weighing platform. This allows toddlers who are able to stand to be weighed safely on a flat surface.

  • Superior Battery Life: Powered by 6 x AA batteries, the M-400 delivers over 100 hours of continuous use (approximately 6,000 weigh-ins), making it the ultimate tool for a full week of community visits without needing a mains connection.

  • High-Accuracy Graduations: To ensure precise monitoring of infant growth, the scale features 5g increments up to 10kg, and 10g increments thereafter, providing the granular data required for neonatal care.

  • Dynamic “Hold” Technology: Infants rarely stay still; the integrated Hold function automatically calculates an average weight, allowing clinicians to capture an accurate reading even when the baby is moving.

  • Lightweight Portability: Weighing just 4kg, the scale is designed for transport. It can be paired with an optional rucksack or carry case to protect the internal loadcells during transit between home visits.

Professional Functionality

  • Tare Function: Easily deduct the weight of blankets, nappies, or clothing to ensure you are viewing only the infant’s true weight.

  • Adjustable Levelling Feet: Ensures a stable and accurate reading on uneven surfaces, which is essential for home-visit environments.

  • Connectivity Options: This model is available with optional Bluetooth connectivity, enabling the wireless transfer of weight data to patient record systems, reducing the risk of manual entry errors.

Frequently Asked Questions

Please see below for answers to frequently asked questions.

A calibration certificate proves the accuracy of your weighing equipment. It is very likely that if accuracy matters in your workplace, certification will be required by your industry regulators. They are straightforward to get hold of though. Just ask our team.

If you are trading or transacting anything by weight, you will probably need to demonstrate your weighing equipment is verified for trade use. This gives your customers confidence in your business and will make sure buying and selling run smoothly. We can help get you with relevant approvals for your equipment.

The answer will vary depending on how your equipment is used. As a minimum, we typically recommend once a year but our team can provide advice based on your individual circumstances.

The International Organization of Legal Metrology (OIML) has established standards for the classification of calibration test weights. Varying from E0 & E1, which are the most accurate to M2 which are commonly used for calibrating platform scales, floor scales and other industrial weighing instruments.

As a rough guide we have listed desired accuracy against class below.

+/- 0.1% – UNclassed Proof Load Test Weights
+/- 0.05% – M3 (Check/calibrate coarse scales)
+/- 0.005% – M1 (Check/calibrate standard scales)
+/- 0.0015% – F2 (Check/calibrate portable balances)
+/- 0.0005% – F1 (Check/calibrate precision balances)
+/- 0.00015% – E2 (Check/calibrate analytical balances)

The choice of weight class depends on the intended use and the level of accuracy required for a particular application. If you’re unsure, talk to our team who can advise you on the right class for your equipment.

If you’re sending a scale back to us for recalibration, it is ideal to use the original packaging. If this is not available choose a sturdy well-padded box to avoid shocks. Where possible, protect the load sensor by removing the weighing pan and any under-pan support and pack these separately in the box. You may be able to use the equipment’s locking pins or screws too.

Do ensure all the paperwork, including your contact details, is included to ensure we can return it once calibration is complete.
