Digital data-logging light meters are precision instruments used to measure illuminance (lux and
foot-candles) in field conditions.
They meet the requirements of CIE spectral sensitivity curves for spectral response. Their
photoelement is cosine-corrected.
The meters are compact and durable units thanks to their simple-to-use design.
The photosensitive element used in these meters consists of a very stable and durable silicon
photodiode and spectral sensitivity filter.
The most important features of the devices include:

maximum resolution of light metering: 0.1 lx (0.01 fc) - LXP-2, 0.01 lx (0.001 fc) - LXP-10B,
0.001 lx (0.0001 fc) - LXP-10A,

high accuracy and fast response time,

Data-hold function for holding the measured values displayed on the screen,

automatic reset,

no need to use correction factors for different light sources, thanks to a very good adjustment of
spectral sensitivity ensuring correct measurements of light intensity regardless of the nature of ra-
diation,

short response times to changing light intensity,

"Peak-hold" function that enables the user to measure the peak signal of light pulse longer than
0.1 s (0.4 s for LXP-2 with probe LP-1) and shorter than 1 s,

automatic power off after 5, 10 or 15 minutes, or auto-off function

measurements of maximum and minimum values,

relative readings,

large and readable display with backlit function;

USB socket for connecting the meter to a PC,

data transmission via wireless (radio) link with an optional adapter OR-1 (only LXP-10B, LXP-10A),

four measuring ranges - LXP-2, five measuring ranges - LXP-10B, six measuring ranges - LXP-10A,

memory space for 99 results (LXP-2) or 999 results (LXP-10B, LXP-10A), that may be read on the
meter or on a PC,

data logger with a logging capacity of 16000 values.
