Light
Meter: Lux Scale, 840006
|
Applications include light
levels in work places, labs and schools, environmental studies,
biology, optics, reflectance and translucence properties of materials.
Compact and portable, can be used to monitor light levels anywhere, or
to check the lux level of a particular light source. Use to check
compliance with ANSI/NFPA 101, (standards for emergency and exit
lighting). Sper Scientific light meters are cosine and color corrected
and have a range of 0.1 to 20,000 lux. Quick and accurate response.
The selenium cell photosensor is hermetically sealed to ensure long
term stability. Large easily legible 4 digit LCD. Also has a data hold
switch to freeze results and a recorder output. Comes with carrying
case, photo-sensor cover, instructions and a 9-Volt battery.
