TES-1335 Digital Light Meter

TES-1335 Digital Light Meter is a reliable device for accurate light intensity measurement, suitable for various indoor and outdoor lighting applications.

  • Measures light intensity up to 400,000 Lux / 40,000 fc
  • 3 3/4 digit LCD with bargraph for easy reading
  • Silicon photodiode sensor with CIE photopic response for accuracy
  • MAX/MIN, peak hold, and data hold functions in a portable design

Description

The TES-1335 Digital Light Meter is a dependable and easy-to-use instrument designed for accurate measurement of light intensity in a wide range of applications, including workplaces, schools, studios, warehouses, and general environmental lighting assessments. It features a 3 3/4 digit LCD with bargraph display, providing clear visual feedback and quick interpretation of readings. Equipped with a high-quality silicon photodiode sensor, the meter supports a broad measuring range of up to 400,000 Lux (40,000 fc), delivering fast, stable, and precise results.

To enhance measurement reliability and user convenience, the TES-1335 includes practical functions such as MAX/MIN recording, peak hold, and data hold, allowing users to capture and analyze light variations effectively. Its spectral sensitivity closely matches the CIE photopic curve, ensuring accurate representation of human eye response to light. Lightweight and portable, the meter is supplied with a 150 cm remote sensor lead, batteries, and a protective carrying case, making it a practical and long-lasting solution for both field and indoor light measurement tasks.
