The Marsden M-900 is a premium portable bed weighing scale for clinical settings where accurate patient weight is critical but moving the patient from the bed is unsafe or impractical. With 600kg capacity and Class III approval under the NAWI Directive, the M-900 supports NHS admission weighing protocols, bariatric bed assessment and drug dosing accuracy for bedbound patients across acute wards, ICUs, hospices and care homes.
Two weigh beams with fold-out ramps allow beds to roll directly onto the scale, with Preset Tare instantly deducting the bed weight to deliver a clean, patient-only reading, removing a common source of clinical calculation error.

Class III approval under the NAWI Directive confirms the M-900 is authorised for clinical monitoring, diagnosis and treatment in NHS and regulated care environments. Preset Tare is critical for accurate drug dosing, particularly for body-weight-dosed medications including IV anaesthetics, anticoagulants and chemotherapy agents, where bed weight deduction must be precise and repeatable on every weighing episode. The portable design supports multi-ward deployment without cross-contamination between weighing sessions, supporting NHS infection control policy.
How does Preset Tare work on the M-900 and why is it clinically important?
Preset Tare allows the known weight of a specific bed to be stored in the indicator. When the bed rolls onto the scale, this value is deducted automatically to show only the patient weight. This eliminates the need to re-weigh the empty bed each session and removes a significant source of dosing calculation error, particularly relevant in ICU and palliative care where drug dosing precision is critical.
Can the M-900 weigh patients in bariatric or profiling beds?
Yes. The M-900's 600kg capacity and fold-out ramp design accommodate most bariatric and profiling bed types. Portability is a key clinical benefit here: the scale comes to the patient rather than requiring any patient transfer, which is important for bariatric patients where manual handling risk is elevated and maintaining patient dignity during the weighing process is a CQC quality expectation.
