Applications

The SECULIFE IT illuminance meters are handy, easy to use and high precision measuring instruments.
They allow the accurate measurement of the illuminance in the unit lx or fc.
Combined with the Luminance Attachment, available as optional accessory, the SECULIFE
used for measuring luminance in the unit cd/m² or fL.
The light sensor is color corrected, i.e. its relative spectral responsivity has been adapted to that of the

human eye V( ). All the important types of light can be measured with high precision, without the necessity
to apply any additional correction factors.
The accuracy of that V(
(M688E) and SECULIFE
Standard Specifications DIN 5032, Part 7. Consequently, the SECULIFE
SECULIFE IT complies with Class B (DIN 5032, part 7 and 8).
The light collector with circular orifice in the photometer head has integrated cosine correction, so that
oblique incident light will be measured accurately.
Both SECULIFE IT/ITC
additional accessories. Especially the SECULIFE
for measuring extremely low light intensities, such as emergency lighting.
The instruments are provided with a measuring value memory with 100 data spaces, which can be read
and processed directly by the keys and the display but also through the integrated USB Port and the
Standard Software supplied with the meters.
lx = Lux
fc = footcandle
