LXP-2 lux meter with calibration certificate WMGBLXP2

The meter is designed to test illuminance up to 20 kLx with max. resolution of 0.1 Lux. In addition, it is possible to save the obtained results in the device's memory, and then transfer data to a computer.

The most important features of the device include:

• maximum resolution LXP-2 light measurement: 0.1 lx (0.01 fc),
• high accuracy and short response time,
• Data-hold function to freeze the displayed measurement values on the screen,
• no need to use correction factors for different light sources thanks to a very good adjustment of spectral sensitivity that guarantees correct measurement of illuminance regardless of the nature of the radiation,
• short response times to changes in illuminance,
• Peak-hold function for measuring the peak signal of a light pulse with a duration longer than 0.4 s and shorter than 1 s,
• automatic power off after 5, 10 or 15
• MIN MAX and MIN MAX measurements,
• REL relative readings,
• large and easy-to-read backlit display,
• USB port for connecting the device to a computer,
• four measurement ranges
• saving 99 results to the memory, which can be read in the meter or computer,
• data logger with 16,000 values and PC readability.
