Description

Reliable illuminance measurements with the LXP-2 light meter

Model for people making basic lighting measurements of indoor and outdoor workplaces. The device works with LP-1 measuring probe (class B) which allows to proceed with measurements in a reliable way. The nonintegrated probe eliminates the influence of the user to the measurement result.

Main features

high resolution up to 0.1 lx
highly accurate measurements
measurements of all types of light sources including:
- LEDs lamps,
- incandescent lamps,
- fluorescent lamps,
- electrodeless lamps,
- high and low-pressure lamps
no need to using correction factors
photodiodes with filters make the spectral sensitivity characteristics well matched to the requirements of C.I.E.

Product functions

data-hold for freezing measuring values
automatic zeroing
peak-hold for freezing the peak signal of light pulse
capable of selecting measuring mode in Lux or FC scale
MAX and MIN results save
relative mode
easy to read large backlit display
USB connection with PC
built-in memory: 99 points
16 000 values records data logger
auto power off

Technical data

Illumination measurement

The result may be displayed in lx or fc. Displaying fc results with reduced resolution due to the display limitations.
