Proper Usage of Solarmeter ® Ultraviolet Radiometer for Lamp Tests

  • Wear UV-block eye protection when checking UV lamps

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

  • Hold sensor close to lamp or acrylic to measure individual lamp MED intensity. Hold sensor at 25cm above bench acrylic with canopy closed (approx body position), for overall canopy measurement

  • Press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at UV source

  • Note reading on LCD and record for future reference.
