Overview of the Reed Instruments R8100SD Data Logging Light Meter
The Reed R8100SD Data Logging Light Meter is a real-time data logger with an integrated SD memory card slot. 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 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 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 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.
