Illuminance Meter, Pocket-Sized, NIST Certified

Pocket-Sized Illuminance (LUX) Meter | NIST Certified

Product Overview

Meet the LX20, a pocket-sized illuminance (LUX) meter that combines unmatched portability with advanced functionality. This NIST-certified instrument is designed for professionals and enthusiasts who require precise and reliable light measurements on the go. Its compact design and versatile features make it an essential tool for a wide range of applications, from ensuring workplace safety to optimizing creative environments.

Versatile Applications

The LX20 is the perfect tool for measuring light levels in various settings:

• Commercial & Industrial: Ensure OSHA compliance in offices, warehouses, and factories to promote a safe and productive work environment.
• Residential & Architectural: Assess ambient light in homes for interior design, energy efficiency audits, and creating comfortable living spaces.
• Photography & Videography: Measure light to set up perfect lighting conditions for photoshoots and film production.
• Horticulture: Monitor light levels in greenhouses and indoor gardens to ensure optimal plant growth.
• Education & Research: Use in science labs and classrooms for experiments and environmental studies.

Key Features & Specifications

• High-Precision Sensor: The LX20 utilizes a silicon photodiode sensor with a spectral response that closely approximates the CIE standard luminous efficiency curve, ensuring accurate readings.
• Wide Measuring Range: Capable of measuring from a faint 0.1 lx up to a bright 403.9 klx, with an impressive accuracy of ±5%.
• Dual Display: Features a clear 4039-count digital display for precise readings and a 41-segment analog bar graph for quickly visualizing light level changes.
• Detachable Stick-Shaped Probe: The slim light sensor can be extended on a 900mm (approx. 3 ft) cord to measure light in hard-to-reach areas or attached directly to the main body for ambient readings. When not in use, it tucks neatly into the unit for secure storage.
• User-Friendly Design: The cleverly designed cover protects the screen and controls when closed and folds flat against the back during use. It also includes essential functions like Data Hold and an Auto Power Save feature that turns the device off after 15 minutes of inactivity to preserve battery life.
