3-in-1 REUSABLE CARD - The EIDEAL UV & UVC Test Card is double-sided. On the one side, you have two tests: UV light and UVC light, which indicate whether a bulb or light is indeed irradiating the type of UV light that it claims. On the other side, you can test any UV or UVC bulb's remaining intensity. Remember UV lights have a life span of about 9000 hours. We recommend storing the card in the packaging sleeve to protect the sensitive test area.
SIMPLE TO USE - These cards have been designed to be simple to use and easy to understand. No confusing instructions and the card gives a clear indication of the test results. Please note that the intensity scale gives an approximate indication of the intensity remaining in a bulb. Should you require a more accurate reading, please use a Radiometer/ Optometer.
HOW TO READ RESULTS: The UV & UVC test has to be observed directly under the light that you are testing. The letters will disappear immediately when not irradiated by the light. The UV Intensity test side can be used in a closed box or directly under the light. This test gives an indication of the UV or UVC remaining in the bulb depending on the time you leave the card exposed to the light. To calculate UV Dose: UV Intensity (μW/cm² - the reading which the card gives you) x Exposure Time (seconds).
DIFFERENT USES/ TESTS - So you have bought this UVC sanitizing wand, but is it emitting the correct wavelength to kill all harmful bacteria as promised? The UV protection film that is installed on your car windows, does it block all UV as claimed? And those UV blocking glasses, are they protecting your eyes? Find out!
DEVELOPED WITH THE CUSTOMER IN MIND - We wanted to create a simple to use card with added value. A lot of thought and investigation went into the planning of this card so that it would be easy to understand and simple to use.
