Environmental Meter | RH / Temp / Light (UV & Lux)

It is recognised that a major cause of damage to museum works of art can be in the light illuminating a room (Ultra violet and visible radiation), with the most damaging being the UV content.To enable curators and conservators to monitor these levels we offer a proven range of instruments.

With regard to light, this meter measures:

1. Proportion of UV present (µW/Lumen)
2. The total amount of UV (µW/M²)
3. The amount of visible light present (Lux).

Allowing you to take action when needed: The amount of UV should be as small as possible, and in general should not exceed 20µW/M² or 75µW/Lumen. Normal museum light levels should be limited to 150-250 Lux. Once measurements have been observed action can be taken, light levels altered, if necessary UV filters fitted to display cases, windows and fluorescent tubes.

This single instrument measures:

1. Humidity (RH) + Absolute humidity (AH)
2. Temperature (Degrees C/F) + Heat Index (HI) and Humidex (Hmdx) (further information in ‘Specification’ tab below)
3. Ultra Violet (UV)
4. Visible Light (LUX)

The large 128×64 OLED Display with automatic brightness control has an easy to use menu system to select more advanced functions.

Data Logging functions (available on 684-765C) enable over 10,000 readings of all four parameters to be automatically taken at selectable intervals (every 10 seconds to 1 hour). The saved data can be transferred to a computer by a USB connection. Software is provided to save the logged data in a CSV format that can be accessed and displayed by many applications.
