Equipped with a vast 10,000fc or 100kLux range, Extech has introduced the SDL400 Light Meter/Datalogger. In addition an adjustable data and sampling rate, the SDL400 provides cosines and color corrected measurements with the accurate silicon photo diodes and a spectral response filter. 

To deliver relative measurements, the meter employs an offset adjustment used for the zero function. The SDL400 stores as many as 99 readings manually and 20M readings on a 2G SD card for use in Excel formatting. Users can take high temperature measurements with the type K/J thermocouple input. 

An expansive backlit LCD display, record/recall min, max, data hold and power off make Extech 's SDL400 a complete light measuring and data logging instrument.
