Hand held with a large, easy to read display the ISO-TECH LUX-1335 digital light meter is a flexible, user friendly instrument for the measurement of light intensity.  It is able to take measurements in the range of 0 to 400000 lux or 0 to 40000 fc and a 4000 count reading with instant bar graph indication. Light is measured using a stable, long-life silicon photodiode combined with a spectral response filter and is fully cosine corrected for angular incidences.

• Light measurement ranging from 0.01 lux~ 0.1 klux / 0.01 fc ~ 0.01 kfc

• Digital and analogue graphical display
• Automatic zeroing
• Meter corrected for spectral relative efficiency
• No manual correction factor calculations for non-standard light sources
• Short rise and fall times
• Peak-hold function
• Selectable scale – Lux or fc
• Auto power off after 30 minutes
• Maximum and minimum measurements
• Relative reading function
