How to test your UVC device

by FrankAug 8th, 20213 mins read

The first step to finding out if your UVC device is working properly is to test it. The best way to do this is with a UVC light meter. This will tell you whether the light output from your UVC device has UVC meter numbers, or if there are any flickering lights. You can also use a UV light tester card as a substitute for the UVC light meter. Then, you need to turn on your UVC device and put the card under the UVC light. If there are changes in colors based on the card instruction, then your UVC device should be fine! But just in case it isn't, here are some things you may want to check:

How to test your UVC device

  • Make sure your UVC tester has been placed properly. The area may be too large for the strength of your product, so make sure to test in smaller areas first.
  • Check if the UV light number is changing on the UVC meter or UV light tester card. This will tell you whether your UV device

Methods to test your UV light device

1. One-time UVC test card: Generic Hospital Grade UVC Test Card

with Patented Dosimeter Technology. Verify The Power of All UVC UV-C Handheld Lights, Wands, Wavelength, for All UVC Equipment.

UVC dosimeter card is a safe and efficient tool that can be used to verify UVC exposure of a surface, or an instrument, in healthcare environments, including patient rooms and surgical suites; in laboratories; and also in food and beverage manufacturing and processing facilities. The technology consists of a photo-chromatic ink that changes color when it is stimulated by certain UVC radiation (253.7 nm).

This card is very reliable and enables fast and safe testing for devices. It is a one-time use card, and you can read the result of the test on it permanently. Another reusable test card will lose its reading after a brief time period. The test card can be left in the room with the lamp, and the reading will remain safe. In addition, a Dosimeter test card can be used as PROOF that your device is fake. Clean your item before putting it in the UV device if possible. To make sure it's working, you can use a UVC light meter or test card. Testing an ultraviolet sterilizing device is not as straightforward as testing a faucet or other item that the UV device will reach within seconds. Don't delay because your own security is necessary.

Don't buy lights and put your life in the hands of fake sanitizers without getting these cards.

Test your bulb using a UVC light device because it has been shown to detect counterfeit goods well but not as reliably when only testing the visual appearance. It seemed that both the test strip and LED light would turn on. I used the UV-C strip by a lit-up bulb, but it did not fluoresce. The GE quartz germicidal UV-C bulb which I use to sterilize masks inside of a cooler after use. To ensure the device is functional, you will need to bring the test strip close to the source (within a few inches) before using it. If after doing so it glows green in the dot in the middle of the card next to UVC, then this confirms that your UV light device works.

3. UVC light meter: Extech SDL470 Short-/Long-wave UV Irradiance Light Meter

with Datalogging, Cosine Correction Filter, Offset Adjustment, Adjustable Data Sampling Rate, Type K/j Thermocouple Input

UVC probe captures short-wave 254nm UV irradiance measurements under a UVC light source

The Extech SDL470 is an inexpensive, handheld light meter that measures UV irradiance in both the UVA and short-wave UVC ranges. The SDL470 has a cosine correction filter and metal housing to protect the sensors from damage. It also features a data-logging feature that records readings with date and time stamps on an SD card (included) in Excel format. This data can be used to analyze trends over time or compare measurements between multiple locations.

How to make sure the UVC device is working?

Make sure it is a UVC tester instead of UVA or UVB

A UVA or UVB tester may measure how much light is being emitted but does not measure the potential for radiation damage to cells. To test a UV device, make sure it is a UVC tester instead of UVA or UVB and clean your item before putting it in the UV device if possible. To make sure it's working, you can use a UVC light meter or test card. Testing an ultraviolet sterilizing device is not as straightforward as testing a faucet or other item that the UV device will reach within seconds. Don't delay because your own security is necessary.

Conclusion

  • Make sure it is a UVC tester instead of UVA or UVB
  • Clean your item before putting it in the UV device if possible
  • To make sure it's working, you can use a UVC light meter or test card. Testing an ultraviolet sterilizing device is not as straightforward as testing a faucet or other item that the UV device will reach within seconds. Don't delay because your own security is necessary.
