Does the CP-UV01 provide an absolute UV measurement?

No. It is intended for visual indication and relative comparison under similar conditions, not as a calibrated UV radiometer.

Frequently asked questions

What does the CP-UV01 show?

It produces a visible green response when suitable ultraviolet input reaches its passive optical conversion structure. The response can be observed directly or recorded with a smartphone.

Does the CP-UV01 measure an absolute UV value?

No. It is a visual indicator for relative comparisons under similar conditions, not a calibrated radiometer and not a substitute for certified measurement equipment.

Does the CP-UV01 require a battery?

No battery or external power is required in the CP-UV01 itself. A smartphone is optional and is used only for recording or app-assisted comparison.

What is included in the Complete Kit?

One CP-UV01 body, one CP-UV01-SA smartphone adapter, and one detachable light shield. A smartphone is not included.
