PCE LMD 5 Light Meter (400,000 Lux)

PCE LMD 5 Light Meter (400,000 Lux)

The PCE-LMD 5 light meter is an optimal mobile solution designed to measure and evaluate illumination levels in an extremely wide measuring range from 0 to 400,000 lux with high sensitivity and accuracy. The device integrates a detachable light sensor probe (silicon photodiode with a spectral filter), helping to quickly and accurately check lighting indicators at various flexible locations without affecting the environment or sample.

Outstanding Features

Comprehensive optical measurement system: The device is equipped with a high-quality silicon photodiode sensor combined with a spectral filter, ensuring absolute accurate collection and analysis of light intensity in a wide measuring range up to 400,000 lux. It supports displaying results in two international units: Lux and Footcandle (fc).

Powerful parameter testing performance:

• Integrates a fast sampling rate (4 Hz) along with a Peak hold function with a sampling rate of 10 microseconds (μs), supporting the measurement of flashing or rapidly changing light sources.
• Provides advanced analysis features such as maximum/minimum (Max/Min) value display and relative value function (REL) compared to a reference sample.

Intelligent operation and connection system:

• Intuitive display interface: Clear backlit LCD screen combined with a visual bargraph next to the numeric value makes tracking light fluctuations easy.
• Large data memory & PC connection: Integrates a data storage memory of up to 32,000 readings. Supports PC connection via Micro-USB port for data transfer, live measurement, and exporting data to CSV format for analysis.

Manufacturing materials and durable structure: Sturdy ergonomic handheld design using high-grade plastic materials, helping to maintain stability in field, workshop, or laboratory working environments.

Energy-optimized operation mechanism: Uses an integrated 3.7V Lithium-ion rechargeable battery, easily rechargeable via a convenient Micro-USB 5V DC port.

Practical Applications

Thanks to its wide measuring range and in-depth analysis features, the PCE LMD 5 is widely applied in many industries and daily life:

• Lighting & Workspace Industry: Testing illuminance levels at offices, production workshops, schools, and hospitals to ensure compliance with lighting safety standards.
• Agriculture & Greenhouse Industry: Measuring and controlling light intensity in high-tech farming areas and greenhouses to optimize plant growth conditions.
• Studio & Photography: Supporting professional light condition testing and calibration in filming and photography studios.
