The new range of digital illuminance meters of the LXP family allows for very accurate measurements of illuminance. Thanks to its accuracy, the LXP-10A lux meter (resolution 0.001 lx) allows, among others, to measure escape routes. Luxmeters have a built-in memory and a number of additional functions to facilitate measurements.
The most important features of the device include:
- high accuracy and short response time, li>
- Data-hold function for keeping the displayed measurement values on the screen,
- no need to use correction factors for different light sources thanks to very good adjustment of spectral sensitivity to ensure correct measurement of illuminance regardless of the type of radiation,< /li>
- short response times to changes in light intensity,
- Peak-hold function for measuring the peak signal of a light pulse with a duration longer than 0.1 s and shorter than 1 s ,
- auto power off after 5, 10 or 15 minutes or disable auto power off,
- MIN MAX and MIN MAX measurements,
- relative REL readings,
- large and easy-to-read backlit display,
- USB port for connecting the device to a computer,
- radio data transmission using the optional OR-1 adapter.
- six measurement ranges,
- saving 999 results in the memory, which can be read in the meter or computer,
- data logger with the possibility of saving 16,000 values with the possibility of reading in PC.
