Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap. Interference filter coating (Metal Oxide) blocks most UVA from response as shown on Spectral Sensitivity Graph.
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 if desired. For reptile lamps also check at "basking" position.
Proper Usage of Solar meter ® Ultraviolet Radiometer for Lamp Aging Tests
- Wear eye protection when checking UV lamps (UV-block wrap around glasses).
- Allow lamps to warm-up prior to taking readings (at least 5 min).
- When checking aging of lamps, keep measuring distance and locations constant.
- Lamps should be replaced when output drops 30% to about 70% of their original (new) readings. Take overall reading at exposure distance, or check individual lamps close to surface. Keep track of hours vs. readings on a chart
