UV-A Irradiance Meter
£495.00
NIST traceable, hand-held UV light irradiance meter with integral sensor.
- Compact, Handheld, and Durable
- Simple Single-Button Operation
- NIST Traceable Accuracy
- LCD Display
Applications include monitoring UV lamp irradiance to help schedule maintenance and testing transmission of shielding, guarding and PPE.
Description
Sensor
The sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400 nm and infrared radiation, because its spectral response only covers the UV-A region from 320 – 400 nm.
Operation
To operate your UV 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.

Instructions for use
- Wear skin and eye protection when checking UV lamps.
- 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.
- Lamps should be replaced when output drops to about 70% of their original readings.
- For curing lamps, hold the meter at the distance you intend your work piece to be cured.
- For transmission testing, take readings with and without materials at a fixed distance.
- When comparing different types of lamps consider readinsgs to be relative rather than absolute.
- Lamps that peak near 365 nm (newer designs) will read higher than lamps that peak near 350 nm.
- 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.
UV Health & Safety
UV safety in the workplace
Ultraviolet equipment is used safely in workplaces every day, and a little planning is all it takes to keep it that way. If you use artificial UV sources at work, there are legal requirements you need to know about.
What the regulations say
In Great Britain, the Control of Artificial Optical Radiation at Work Regulations 2010 (AOR 2010) apply to employers whose workers may be exposed to artificial optical radiation, including UV. They implement the EU’s Directive 2006/25/EC, which sets similar minimum health and safety standards across Europe.
In practice, employers are expected to:
- Assess the risk from UV sources used in the workplace
- Eliminate or reduce exposure so far as is reasonably practicable
- Keep exposure within the legal limits
- Provide information and training to anyone who may be affected
- Review the assessment when equipment, processes or people change
None of this is meant to put you off using UV. A clear assessment, the right controls and informed staff are usually all that’s needed, and it protects your people and your business.
