Why Replace the Measuring Pen?

The CaratScreenPen V1 operates using a small amount of harmless electrolyte fluid contained inside the measuring pen. Due to the limited internal volume, the pen has a typical lifespan of approximately 3–6 months, depending on frequency of use.

Once the electrolyte fluid level drops below a certain threshold, reliable measurement can no longer be guaranteed.

You should replace the pen if you notice:

• Deviations in measurement values
• Calibration errors
• Inconsistent or unstable results
• Replacing the pen ensures continued accuracy and dependable gold testing performance.

Important Usage & Care Instructions

• Keep the measuring pen closed when not in use.
• Avoid storing at high temperatures, as this accelerates evaporation of the electrolyte fluid.
• Do not clean the measuring pen, as this may damage the electrolyte and affect measurement accuracy.
• Slight leakage during transport or prolonged storage is normal and harmless. Simply wipe away excess liquid with a cloth.
• If leakage occurs during the measurement process, please contact customer support.
