Have you ever needed a reliable way to measure light levels for your projects? Whether you’re a lighting professional, photographer, or an engineer, you know how crucial accurate light measurement can be. Enter the Extech SDL400 Light Meter SD Logger—a tool designed with both precision and convenience in mind.
What Makes Extech SDL400 Stand Out?
Wide Range Light Measurement
The Extech SDL400 offers a broad light measurement range up to 10,000 Fc or 100,000 Lux. This flexibility is perfect for a variety of applications, from assessing indoor lighting conditions to measuring outdoor sunlight.
Precision Silicon Photo Diode
Utilizing a precision silicon photo diode and a spectral response filter, this light meter provides highly accurate readings. Whether you’re testing LEDs, fluorescents, or natural sunlight, you can trust the SDL400 to give you dependable results.
Datalogger with Date/Time Stamp
One of the standout features is the built-in datalogger. The SDL400 date/time stamps each measurement and stores readings on an SD card in Excel format. This functionality simplifies data transfer to a PC, making it ideal for extensive fieldwork or long-term monitoring projects.
User-Friendly Offset Adjustment
The offset adjustment feature allows you to zero the instrument to make relative measurements. This capability is especially useful when you need to compare light levels across different environments or at various times.
Cosine and Color-Corrected Measurements
Accurate light measurement isn’t just about lux or foot-candles; it’s also about precision in different lighting conditions. The SDL400 is cosine and color-corrected to ensure even more accurate data.
User Experience
Ease of Use
From setup to data logging, the Extech SDL400 is designed to be user-friendly. The intuitive interface and straightforward controls mean you won’t have to spend hours reading the manual before you can get started.
