        Detector SIC/IF Photodiode

        Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap.
        Interference filter coating (Metal Oxide) blocks UV above erythermal response as show 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. For tanning beds place meter at body position. Note reading on LCD and record if desired.

        Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under "typical" service load, the battery should last about 2 years.

        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 Eeff intensity. Hold sensor at 25 cm above bench with canopy closed for body position reading.
        When checking aging of lamps, keep measuring distance and locations constant
