ATP LX-3809 LED Light Meter

The ATP LX-3809 LED Light Meter provides clear illuminance measurements in lux or footcandles for workplace checks, surveys and routine monitoring. Its silicon photodiode sensor uses an LED spectral filter with sensitivity relative to 550 nm in line with JIS C 1609-1993. A selectable light source setting also allows measurements of LED or standard light sources.

For practical work on site, the meter offers manual or automatic ranging and covers lux measurements up to 400,000 lux. The 50 mm LCD includes a backlight and 40-segment bargraph, helping users follow readings and spot changes during a survey. Data functions include hold, minimum, maximum and average readings, while over-range indication and zero adjustment support straightforward operation.

The ATP LX-3809 LED Light Meter also uses cosine correction to support readings when light reaches the sensor from different angles. Its fixed sensor connects through an approximately 1.5 metre coiled cable, making it easier to position the sensor while keeping the main meter in hand. With automatic power-off, a user-disable option and four AA alkaline batteries, it is suited to regular environmental, health and safety and industrial lighting checks.

 

Key Benefits
  • Measures illuminance in either lux or footcandles to suit different survey requirements.
  • User-selectable LED or standard light source settings support checks across different lighting types.
  • Manual and automatic ranging help users work across a wide spread of light levels.
  • Backlit LCD improves display visibility when working in dim areas.
  • 40-segment bargraph gives a quick visual indication of changes in measured light levels.
  • Data hold keeps a reading on screen when it needs to be noted or reviewed.
  • Minimum, maximum and average functions help users compare readings during routine surveys.
  • Cosine correction supports more consistent measurements when light reaches the sensor from different angles.
  • Fixed sensor lead allows the sensing head to be positioned away from the meter body during checks.
  • Automatic power-off helps manage battery use and can be disabled by the user when required.

 

Common Applications

ATP LX-3809 LED Light Meter is suitable for a range of testing, maintenance and inspection tasks, including:

  • Workplace lighting checks
  • Site lighting surveys
  • Lighting audits
  • Health and safety checks
  • Routine illuminance surveys
  • Environmental monitoring
  • Industrial lighting applications
  • Comparing light levels between rooms, walkways and work areas
