PCE-LMD 100 Luminance Meter (0 ~ +50,000 cd/m2; 0.01 ~ 1 cd/m2)

PCE-LMD 100 Luminance Meter (0 ~ +50,000 cd/m2; 0.01 ~ 1 cd/m2)

The PCE-LMD 100 luminance meter is an optimal solution designed to analyze and evaluate the luminous intensity per unit area (in cd/m2) of surfaces such as monitor matrices, TV screens, X-ray film viewers (negatoscopes), display panels, and LED backlights. The device operates based on an advanced photometric measurement method with a detached sensor probe, ensuring high accuracy independent of the spatial distribution or backlight system of the tested surface.

Key Features

High-precision optical measurement system: The device achieves Class A accuracy according to strict standards DIN 5032-7 and CIE TC-2.2, ensuring extremely reliable data collection and analysis.

Powerful parameter testing performance:

• Provides a wide measuring range from 0 to 50,000 cd/m2, divided into flexible ranges with high resolution (0.01 cd/m2 for ranges from 0 to 500 cd/m2 and 1 cd/m2 for ranges from 500 to 50,000 cd/m2).
• Supports testing the grayscale reproduction of displays according to the DICOM GSDF function, which is critical in medical applications.

Smart operation and connection system:

• Multi-function button integrated probe: The measuring sensor comes with a direct push-button allowing users to trigger measurements, save results, or configure measuring methods quickly right at the probe.
• Large data memory: Equipped with an 8 GB Micro-SD memory card, allowing storage and automatic recording of measurement results into text documents conveniently.
• Modern communication port: Supports a Micro-USB connection port to easily transfer data and provide a stable power supply.

Durable materials and structure: Compact and sturdy handheld design, accompanied by a specialized optical tube sensor probe and a professional protective carrying case, optimized for mobile or laboratory testing work.

Power-optimized operation mechanism: Uses flexible power sources from an integrated rechargeable battery or USB 5V DC power supply, meeting continuous extended working shifts.

Practical Applications

Thanks to its Class A precision and specialized measurement capabilities for luminescent surfaces, the PCE-LMD 100 is widely applied across multiple fields:

• Medical & Diagnostic Imaging: Periodic testing of brightness and quality for specialized medical displays and X-ray film viewers (negatoskop) to ensure compliance with safety diagnostic regulations.
• IT & Graphic Design: Measuring and evaluating uniformity and brightness of computer screens, TV displays, and digital display devices in laboratories or production workshops.
• Lighting & Advertising Industry: Testing luminous intensity of large LED billboards, video walls, or other self-illuminating surfaces.
