Q: Does UV-C light go through glass or windows?
A: Standard window glass blocks almost 100% of UV-C light according to the IUVA.
(
Normal glass, as used in a window, is transparent to UV radiation to a wavelength of
about 330 nm (UV-A). The transparency is quite high so almost all UV-A light will pass
through glass. Below 330 nm (UV-B and UV-C), almost 100% is blocked by normal
glass.
Q: Can I use an ATP Meter with the UV MAX
A: Yes, it can be used to measure how clean a surface is
Q: Can I use a response card with the UV MAX?
A: Yes, it can be used to indicate the correct dosage (intensity x
time x distance) has been applied to a surface
Q: What is the difference between bacteria and sporicidal modes?
A: Your UV-MAX Ultra is equipped with two modes of operation, Bacterial and Sporicidal. It is
important for the user to understand the difference between the two. For sporicidal mode, the
time function is doubled. Spores are the more difficult microorganism to target due to the
composition of the cell membrane. In order to be categorized as a spore a rigid protective layer
on the cell membrane must exist. Most common bacteria and viruses do not have this
protective layer or have a layer of less rigid protection like lipids and are much easier to
deactivate using UV-C light. A common example of a sporicidal target is Clostridium difficile, or
C. Diff.
Below is a chart to illustrate ease of deactivation among common organisms.
