UVA Irradiance Meter
NIST traceable, hand-held UV light irradiance meter with an integral sensor. Compact and durable for single-handed use.
- Measure UV in the wavelength range of 320 – 400nm
- Measurements are shown in mW/cm2
- Supplied with a certificate of calibration
Typical applications include monitoring drop off of UV bulbs and tubes, transmission testing of PPE, screens and guards and natural sunlight measurements.
Please note this meter should not be used for checking occupational UV light exposure, please contact us if you are looking to make health and safety measurements.
Features & Specifications
The UVA Irradiance Meter provides precise measurement of UVA light intensity, essential for quality control, inspection, and laboratory environments. This compact, user-friendly device ensures accurate, reliable readings of UVA irradiance, helping users monitor and control UV exposure in sensitive applications. With a clear display and high sensitivity, the UVA Irradiance Meter supports various applications where UVA intensity measurement is critical, enhancing operational standards and ensuring consistent UV performance.
The sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400nm and infrared radiation, because its spectral response only covers the UVA region from 320-400nm.
To operate your UVA irradiance meter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results. Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need for battery replacement. Under typical service load, a standard 9V battery will last approximately 2 years.
- Wear eye protection when checking UV lamps (glasses that provide wrap around protection are ideal).
- Allow lamps to warm-up prior to taking readings (at least 5 minutes).
- When checking lamp aging, make sure to use the same location and distance to ensure accurate readings.
- For curing lamps, hold the meter at the distance you intend your work piece to be cured.
- For acrylic testing, take readings with and without acrylic at a fixed distance.
- When comparing different types of lamps consider readings to be relative rather than absolute.
- Lamps that peak near 365nm (newer designs) will read higher than lamps that peak near 350nm.
- Do not subject the meter to extremes in temperature, humidity, shock or dust.
- Use a dry, soft cloth to clean the instrument. Keep sensor free of oil, dirt, etc.
