2515.60 Battery box
Lux meter YF 1065
This digital lux meter is a robust and handy item provi-
ded with a separate safe-sealed photodetector for max-
imum stability. The photodetector has good spatial
response so that it will respond to illumination from all
2515.60
directions. It is supplied with an analog output signal for
connection to a chart recorder or other data collection
instrument. This is useful when experimenting e.g. with
photosynthesis. It is supplied complete with a battery
and a convenient carrying case. LCD-display, battery
powered and with separate photodetector.
Measuring ranges: 0-200 lux, 0-2000 lux,
0-20000 lux.
The angular response
follows the cosine
response with the
following deviations: 30 degrees, less than +/-2%.
1888.20
60 degrees, less than +/-7%.
80 degrees, less than +/-25%.
Provided with a “hold” function
for convenient measurement.
Analog output: Jack connections (4 mm).
Size, instrument: 119 x 64 x 26 mm.
Photodetector: 125 x 66 x 36 mm.
