Elsec Environmental Monitor & Data Logger

DescriptionReplaces 4 separate instruments:
Ultra Violet (UV) level – Visible Light (Lux or Foot-candles) – % Relative Humidity – Dew point – Temperature (°C or °F)
Sized like a small mobile phone – Easy one handed operation – Large, easy to read display – Maximum & minimum with time – Optional data logging
Method of radiation detectionTwin silicon photodiodes connected to single chip microprocessor
Visible wavelength range400-700 nM (CIE response). No correction required for different light sources
