Pocket Illuminance Meter

Regular price $192.32 $0.00 Unit price per

This instrument is a pocket-sized illuminance (LUX) meter featuring unmatched functionality and portability.

It can be used for a wide range of applications in offices, homes,  commercial buildings and other locations where light measurement is needed.

The LX20 has a measuring range of 0.1lx~403.9klx and accuracy of ±5 %. It features a 4039 count digital display with a 41-segment bar graph. The device has a stick-shaped light sensor that can be extended separately or attached to the main body for ambient light measurement, and tucks into the unit for storage, enabling measurement of a narrow position or area. The cleverly designed cover folds flat in back of the unit when in use, and protects the unit when closed.

  • Small stick shape sensor probe
  • 4039 counts with analog bar graph
  • Silicon photodiode
  • Measuring range 0.1lx~9klx
  • Data hold
  • Auto power save (15min after last operation)
  • Cord length 900mm
