ILLUMINANCE METER

Introduction:

A high-performance Class A illuminance meter designed for highly accurate measurements in industrial environments, public facilities and other demanding applications. When used in combination with the LP-10A measuring probe, the instrument provides the highest level of measurement accuracy. The device supports wireless data transfer to Sonel Reader PC software, as well as USB connectivity, making it convenient for data analysis, documentation and measurement management.

Main Features:

• Class A measurements for highly accurate illuminance testing.
• High resolution of up to 0.001 lx.
• Accurate measurements for all major types of light sources, including: LED lamps, Incandescent lamps, Fluorescent lamps, Electrodeless lamps, High-pressure lamps, Low-pressure lamps.
• No correction factors required.
• Photodiodes with optical filters provide spectral sensitivity characteristics closely matched to C.I.E. requirements.
• Data Hold function for freezing measurement readings.
• Automatic zeroing for convenient and reliable measurements.
• Peak Hold function for capturing and freezing peak light-pulse signals.
• Selectable measurement units: Lux (lx) or Foot-candles (FC).
• MAX/MIN function for recording maximum and minimum measurement values.
• Relative measurement mode for comparative measurements.
• Large, easy-to-read backlit display.
• USB connection for communication with a PC.
• Wireless connectivity for convenient data transfer.
• Built-in memory: LXP-2: up to 99 measurement points and LXP-10A / LXP-10B: up to 999 measurement points
• Data logger capable of recording up to 16,000 measurement values.
• Automatic power-off function to conserve battery life.

The combination of high measurement accuracy, broad light-source compatibility, advanced data-recording capabilities and wireless communication makes this instrument suitable for professional illuminance measurements across a wide range of industrial and public applications.
