Sensor/Detector
Silicon Carbide (SIC) Photodiode packaged
in hermetically sealed UV glass window
cap.
Interference filter blocks UVA and UVB
from response as show on Spectral Sensitivity
Graph.
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 Lamp Tests
- Wear UV-block eye, face, hand protection
when checking UVC lamps.
- Allow lamps to warm-up prior to taking
readings (at least 5 min).
- Hold sensor close to lamp to measure individual
lamp UVC intensity. Hold sensor at distance
from lamp(s) for effective sterilization intensity.
- When checking aging of lamps, keep measuring
distance and locations constant.
- Lamps should be replaced when output drops
to about 70% of their original (new) readings.
- If unsure of what original new values were,
replace a lamp with new one and compare old
one.
- Do not subject the meter to extremes in
temperature, humidity, shock or dust.
- Use a dry, soft cloth to clean the intrument.
Keep sensor free of oil, dirt, etc.
|
| Note:
Sensor is completely solar blind
to UVB, UVA, visible, and IR. Meter will read
000 pointing to non-UVC sources, including sun,
floodlamps, etc. |
