Proper Usage of Solarmeter ® Ultraviolet Radiometer for Lamp Aging Tests

  • Wear actinic eye protection when checking blue lamps.

  • Allow lamps to warm-up prior to taking readings (at least 5 min).

  • Hold meter integral sensor close to source to measure individual lamp or LED intensity. Hold sensor at working distance from source for effective intensity.

  • When checking aging of lamps, keep measuring distance and locations constant.

  • Lamps should be replaced when output drops to about 70% of their original (new) readings.

  • If unsure of what new values were, replace a lamp with new one and compare old one.

  • Do not subject the meter to extremes in temperature, humidity, shock or dust.
