The Model 6.5 UV Index Meter uses a Silicon Carbide (SiC) Photodiode under a hermetically sealed UV glass window cap with Eeff (erythemally effective) filter and diffuser. Applications include monitoring instantaneous UV index measurement, UV index comparison, monitoring reptile lamp intensity and aging, monitoring uv lamp intensity and aging, and UV index tracking over time. To operate, 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 approximately 2 years.
