How does a UV fast check strip work?
They are the first product that can be used to determine levels of UV dose with a simple, visual inspection due to the 5 separate color changing zones. Each of the 5 zones begin to change color after a specific amount of UV dose has been received. First the “1” zone begins turning from yellow to blue.
How to control the flow of UV light?
Your UV unit has to handle the capacity that will be flowing through it. But you might want to use smaller lines/fittings to control the flow VOLUME (gallons per minute) through the UV unit. I solved the capacity issue by splitting the system after the pump into potable (human consumable) and utility water.
What happens if you leave a UV light on too long?
If water flow is too slow or ceases all together, this can allow the lamp inside the UV to heat up to a point that blows the filament or simply damages the lamp where by it will not light (often leaving dark scorch marks if not blowing the filament). This can also permanently damage an electronic ballast, especially if left ‘on’ after this failure.
What to do if your UV sterilizer bulb does not work?
Often when I came across a UV Sterilizer where the replacement bulb did not work (especially if the bulb/lamp inside already ceased functioning), I would use a second bulb, and if this bulb failed, it was rather obvious I needed to look into what may be the problem with the UV itself, not the lamp/bulb. Failed Ballast.
Which is the best UVC Indicator test strip?
Detect between 320-400nm UVA/UVB on one scale, and 254-280nm UVC on another from the same reusable UV test card With an increasing number of fake and defective germicidal UVC products on the market QuantaDose™ provides you with real-time results for super fast verification/validation purposes.
How are UV strips used to measure dose?
The CON-TROL-CURE® UV FASTCHECK™ STRIPS ‘ clearly identifiable color change enables users to visually differentiate the dose differences. To measure the dose even more precisely, use a spectrophotometer to record color change by the CON-TROL-CURE® UV FASTCHECK™ STRIPS.
How does the UV / UVC test card work?
The UV/UVC test card is based on the principle of molecular change. When the energy of a photochromic molecule absorbs energy from ultraviolet light, the structure of the molecule changes, resulting in a change in the reflected light wavelength, which ultimately changes the color of the substance.
