Overview of the Reed Instruments R8100SD-NIST Data Logging Light Meter
The Reed R8100SD-NIST Data Logging Light Meter is a real-time data logger with an integrated SD memory card slot and NIST Calibration Certificate. It can measure and record ambient light levels in Foot Candles or Lux and contact temperature with optional Type J/K thermocouple sensors. The R8100SD-NIST has a wide measurement range of up to 100,000 Lux (10,000 Foot-candles) and features data hold, min/max functions, and an easy-to-read backlit LCD display. The R8100SD-NIST can manually record up to 99 readings or automatically by selecting the desired sample rate from 1 to 3600 seconds. Raw data can be directly transferred from the SD card as an Excel file which can be viewed without needing any additional software. Optional accessories include a tripod and AC adaptor for continuous long-term monitoring.
The R8100SD-NIST is also available as a kit that includes the meter, 16 GB SD Memory Card, and AC Power Adapter. Check out the R8100SD-KIT Here.
