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.
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.
