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