A monitor name alone does not tell you which cuff is in the box. Compare the arm range for the exact model and bundle, then check that the retailer is offering the same version.
Start with the documented arm range
Look up the arm-circumference range in the manufacturer manual. A 22–42 cm cuff and a 22–32 cm cuff are different choices even when the monitor names look similar. Use the cuff finder to narrow the listed products by the documented range.
Check what is included
A compatible larger cuff may be available separately. The directory distinguishes manufacturer-listed replacement accessories from the cuff supplied with a monitor; a retailer bundle may differ.
Match the exact model
Read the model code on the box or monitor label. A marketing name such as M2 can cover more than one version. Only use a documented compatibility relationship when choosing a replacement cuff.
See the documented blood pressure monitors & cuffs options or match a cuff by model and size.
