Solarmeter Model 6.5 UV Index Meter
This compact, durable, handheld meter is ideal for monitoring instantaneous UV index, measuring solar intensity in terms of UV index, tracking UV index over time, and monitoring UV lamp intensity and aging. The meter is equipped with a Silicon Carbide (SiC) Photodiode under a hermetically sealed UV glass window cap with Eeff (Erythemally Effective) filter and diffuser. To use, simply aim the sensor window directly at a UV source and then press and hold the button on the front of the meter. NIST Traceable accuracy.
