Thiết bị đo cường độ ánh sáng và tia cực tím UV ELSEC 7650 UV & Light Monitor
Measures and displays visible light (Lux or Foot candles), UV light (mW/M² and µW/lumen). Similar to 765 but without humidity and temperature sensors.
The 7650C (with logging) is the same as 7650 with data logging capacity for over 70,000 readings of all parameters. No special software is required, logged information is stored on an internal USB Flash disc and the data can be downloaded onto a PC and viewed with any spreadsheet (Excel etc). A free application (RView) is also available for download that displays the data as a zoomable graph that can be saved as an image for inclusion in documents and/or printed.
The 7650 replaces the obsolete 7640
