Gossen-Metrawatt Light Meter, 19999lx Maximum Light Level, 0.001lx Minimum Light Level - M537G

This light metre provides precise measurement of illuminance across a very wide dynamic range for professional photometric assessment. Designed for field and laboratory environments, it quantifies light levels from near-dark conditions to bright interiors using a single handheld instrument. The unit is powered by a common 1.5 V cell and is suitable for users requiring standardised measurement procedures.

Features and Benefits:

• *Made in Germany
• 2.5% accuracy delivers dependable numerical results for assessments
• 19999 lx range enables measurements in bright illumination settings
• 0.001 lx sensitivity detects extremely low light for dark-scene evaluation
• 1.5 V power allows operation from a widely available cell
• Meets multiple standards to support formal measurement protocols

Applications

• Suitable for workplace lighting compliance checks
• Ideal for photographic exposure assessment in studios
• Used for maintenance of architectural lighting installations
• Can be used for night-time external illumination surveys
• Appropriate for quality control in lighting manufacturing

What accuracy can I expect during routine measurements?

The instrument provides an accuracy of 2.5% under specified conditions allowing precise comparison against reference values.

Which calibration or accreditation standards relate to its measurement validity?

It aligns with recognised metrological and photometric standards including DIN EN 13032-1 Appendix B and ISO/CIE 19476 for measurement practice.

What operating illumination limits does the unit cover?

The device measures from 0.001 lx at the low end up to 19999 lx at the high end, enabling use across very low to high light scenarios.

How is the device powered and what are the implications for field use?
