One question we hear often: how do I know my meter and strips are actually reading correctly? That's what the WaveSense KeyNote Control solutions are for. Available in Normal and High levels in 6 mL bottles, they let you confirm your system is working before you trust a result — worth using when you open a new vial of strips, drop your meter, or simply want peace of mind. It's a small step that protects the reliability of every reading afterward.

Buying the strips, meter, and control solution together means fewer compatibility headaches and no scrambling when your current pack runs low. Because these are consumable supplies used daily, keeping a spare pack of strips and a control bottle on hand is the simplest way to avoid a gap in your testing schedule.
