Hamamatsu #G5842 UV SENSOR/FILTER
The G5842 is a semiconductor UV sensor consisting of a GaAsP photodiode chip and a UV filter. The G5842 is completely insensitive to visible light longer than 400 nm and infrared radiation since its spectral response covers only the UV region from 260 to 400 nm. Applications of the G5842 include solar UV detection, as the spectral response is well matched to the solar UV spectrum, and tanning lamps peaking near 365 nm ("new era" fluorescent and "high pressure" HID).
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.
