What is a column scale?

A column scale is a medical weighing scale with a column mounted indicator, meaning the weight reading is displayed at waist level for the user.

Column scales can save the user time and effort as it means there is no need to bend down to operate the scale. Column scales can also be fitted with height measures, measures, meaning BMI is easy to calculate. For medical use, column scales must be Class III Approved.

What are Class III Approved scales?

Class III Approved scales are weighing scales that have been tested and calibrated to a specific standard, in accordance with the Non-Automatic Weighing Instruments (NAWI) directive. This requires ‘all scales used in the determination of mass in the practice of medicine patients for the purpose of monitoring, diagnosis and medical treatment’ to be Class III Approved, along with five other weighing situations where Approved scales are needed.

Class III Approved scales undergo a rigorous testing programme by an EU Notified Body. This extensive testing provides assurance to the user that the scale meets the required level or accuracy, reliability and repeatability. Find out more here.

All Marsden professional column scales are Class III Approved.

How accurate does my column scale need to be?

An incorrect weight reading in a medical context could be a matter of life and death - so the UK Weighing Federation (UKWF) has recommended that specific scale accuracies are used for each medical weighing application.

If the scale is being used for checking adult weight records, the scale should be accurate to at least 500g; for regular monitoring to assess weight change or measuring weight to assist medical diagnosis, at least 200g; and when measuring weight for critical treatment (dialysis etc), readings should be to the nearest 50g/100g.
