Sensor
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.
Operation
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. |

Proper
Usage of Solarmeter ® Ultraviolet Radiometer
for low level UV measurements.
- When checking home,
business, school, or car window UV transmission,
take reading through window or film and compare
to outdoor reading. Note: The sensitive Model
5.7 reading only goes up to 1999 uW/cm²,
wheras full sunlight can exceed 5000 uW/cm²...
or 5.0 mW/cm² on a Model 5.0 meter.
- For household lighting
including compact fluorescents, take reading
near lamps and again at several inches or
feet distance, to see how far away the UV
falls below 1 uW/cm².
- For gym or stadium
lighting take readings at floor level. If
concerned about amount of UV, ask the owners
to have UV-block shields installed under the
lamps.
- Do not subject the
meter to extremes in temperature, humidity,
shock or dust. Store meter away from humidity
when not in use.
- Use a dry,
soft cloth to clean the intrument. Keep sensor
free of oil, dirt, etc.
