Environmental Monitor (Visible Light, Ultraviolet, Temperature, Humidity)

  • 765 - without logging
  • 765C - with logging

Elsec Environmental Monitor is an hand-sized instrument with an easy to read display.
The world standard instrument for museums, art galleries conservators or any application requiring a controlled environment.

Measures and displays:
- Visible light (Lux or Foot-candles)
- Ultra Violet light (mW/M² or µW/lumen)
- Temperature (°C or °F)
- Humidity (%RH)

Other features:
- Replaces 4 separate instruments (thermometer, hygrometer, ultravioletmeter, luxmeter)
- Easy one handed operation
- Sized like a small mobile phone
- Solid metal construction

Models: 765 (with logging) | 765C (without logging)

The 765C  model (with logging) has data logging capacity for over 70,000 readings of all 4 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 (available for download) displays the data as a zoomable graph and can be saved as an image for inclusion in documents and/or printed.
