Extech SDL400 NIST Light Meter Datalogger 10000 Fc 2 GB SD Card

The Extech SDL400-NIST Light Meter Datalogger offers professional-grade accuracy for measuring illumination levels in industrial, commercial, and laboratory environments. With its broad measurement range up to 10,000 foot-candles (100,000 Lux), this meter is ideal for precision lighting assessments. Its cosine and color-corrected sensor ensures reliable readings under various lighting conditions, making it suitable for diverse applications.

This instrument utilizes a precision silicon photodiode and spectral response filter for consistent performance. Measurements can be viewed on a large, backlit LCD display, with the option to manually record 99 readings or log over 20 million data points via the included 2 GB SD card. A zero-offset adjustment function enables accurate relative measurements, while adjustable sampling rates allow for flexible data capture.

With built-in support for Type K/J thermocouple probes, the SDL400-NIST can also record high-temperature environments, enhancing its versatility. Features like MIN/MAX recording, data hold, auto power-off, and USB PC interface add further utility. Supplied with a NIST calibration certificate, it’s ready for regulated environments from day one.
