6-in-1 QUANTADOSE® Multi-Wavelength UV Test Card – Light Meter

Description

Product Overview

The QUANTADOSE® 6‑in‑1 Multi‑Wavelength UV Test Card is a reusable professional-grade tool designed to detect and differentiate the full spectrum of ultraviolet radiation—from UVA (315‑400 nm) through UVB (280‑315 nm) to UVC (200‑280 nm) and the emerging Far‑UVC band (200‑230 nm). Constructed from a high‑quality, chemically stable polymer matrix, the card incorporates three distinct photochromic analyte strips that respond instantly to specific wavelength ranges. When exposed to artificial or natural UV sources, the strips transition from a clear state to vivid colors—red‑pink for long‑wave UVA/UVB, green‑yellow for short‑wave UVC, and a neutral shade for broad‑band exposure—providing a visual cue that is easy to interpret without specialized equipment. The card measures 3.37 × 0.06 × 2.13 inches and weighs just 1.13 oz, making it portable enough for field work yet robust enough for repeated laboratory cycles. Its design includes a central UVGI intensity test zone that briefly displays the letters “UV” when exposed to a minimum of 300 µW at 254 nm, confirming that a UVC source meets safety standards. The back side features a dedicated Far‑UVC beam detector, the largest short‑wave luminescent surface available on the market, enabling precise placement of Far‑UVC fixtures in occupied spaces.

Usage

Engineers, safety officers, educators, and researchers can employ the QUANTADOSE test card in a wide range of scenarios. In laboratory environments, it serves as a quick verification tool for UV lamps, LED arrays, and sterilization chambers, ensuring that emitted wavelengths match specifications before samples are processed. Industrial users rely on the card to validate UV‑blocking claims for sunglasses, window tints, and protective films, as well as to monitor the performance of UV curing systems in manufacturing lines. In educational settings, the card becomes an interactive teaching aid, allowing students to observe real‑time color changes as they experiment with different UV sources, reinforcing concepts of photon energy and material interaction. Field technicians can also use the card to assess outdoor UV exposure levels on construction sites, outdoor equipment, and personal protective equipment, helping to maintain compliance with occupational health guidelines. The card’s reusable nature eliminates the need for disposable strips, reducing waste and cost over time.

FAQ

How does the color change indicate specific UV wavelengths?

Each photochromic strip is formulated to react to a defined wavelength band. The long‑wave strip turns red‑pink when exposed to UVA/UVB (300‑395 nm), the short‑wave strip turns green‑yellow under UVC (220‑275 nm), and the broad‑band strip adopts a neutral shade after exposure to any UV between 200‑400 nm. By matching the observed color to the known response, users can identify which part of the spectrum is present.

Can the card be used with natural sunlight?

Yes. The card responds to both artificial UV sources and natural sunlight. When placed in direct sunlight, the broad‑band strip will develop a shade proportional to the cumulative UV dose, while the wavelength‑specific strips will display their characteristic colors if the solar UV intensity falls within their sensitivity ranges.

What is the recommended cleaning method after repeated use?

Wipe the card gently with a soft, lint‑free cloth dampened with isopropyl alcohol (≤70 %). Avoid abrasive cleaners or prolonged immersion, as these can damage the photochromic layers. Allow the card to air‑dry completely before the next measurement.

How many exposure cycles can the card endure before performance degrades?

Under normal laboratory conditions, the QUANTADOSE card maintains accurate color response for over 1,000 exposure cycles. Performance may begin to decline only after extreme UV intensities or prolonged exposure beyond the specified limits, at which point the manufacturer recommends replacement.

Is the card compatible with UV‑blocking eyewear testing?

Absolutely. By placing the eyewear between the UV source and the card, users can observe whether the long‑wave strip remains clear (indicating effective blocking) or changes color (indicating transmission). This method provides a quick, visual confirmation of compliance with safety standards for sunglasses and protective lenses.
