Description

E4-X Hagner Digital Luxmeter

The E4-X Hagner Digital Luxmeter is a high-precision instrument designed to measure illuminance from 0.01 to 200,000 lux—perfect for both field and laboratory use.

Key Features:

  • Precision Measurement: Covers a wide range of 0.01 – 200,000 lux.
  • Remote Detector: A 2-metre flexible lead ensures ease of use.
  • Cosine Correction: Fully aligned with CIE standards for accurate measurements.
  • Stable & Reliable: Uses a long-life silicon photodiode, reducing the need for recalibration.
  • Built-in Temperature Compensation: Ensures consistent accuracy in varying conditions.
  • Hold Function: Retain the display value for convenient reading.
  • Versatile Connectivity:
    • DC-input for battery eliminator.
    • Output for loggers, computers, recorders, and oscilloscopes.

 

Compatibility with Hagner Special Detectors:

The standard connector allows the use of multiple Hagner Special Detectors, including:

  • Fibre optic
  • UV-A, UV-B & UV-C
  • Infrared (IR)
  • Hemicylindrical Detectors

 

Additionally, the remote detector supports:

  • SA-1 Light Intensity Adaptor – Measures light intensity and angular distribution.
  • SA-2 Adaptor – Ideal for image screens and light tables.
