765 environmental monitor

765 environmental monitor


The 765 environmental monitor measures and displays visible light (Lux or Foot-candles), UV light (mW/M² or µW/lumen), temperature (°C or °F) and humidity (%RH).

Traditionally UV has been measured in museums as the proportion of ultraviolet present. The damage is done by the total amount of UV falling on the object, so it is useful to be able to measure this directly. This makes the 765 environmental monitor essential for museum monitoring as it displays proportional UV (µW/lumen) and the total amount of UV (mW/M²) at the touch of a button.

This handheld is also available with data logging capacity for over 70,000 readings of all 4 parameters in the form of 765C. When logging data the unit can be turned off to save power and the built in clock will turn the unit on whenever a reading needs to be taken, this enables a 765C to be left taking readings for months at a time. 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 zoom able graph that can be saved as an image for inclusion in documents and/or printed.

Much trouble has been taken to make the 765 environmental monitor as easy to use as possible. Anyone can take measurements straight out of the box with little, if any, reference to the instruction manual. The appropriate button is pushed depending on the measurement required and the reading is taken. The unit automatically turns off 20 seconds after the last reading unless a button is held down for over 3 seconds, this causes continuous measurements to be taken until another button is pressed. The large OLED display enables an easy to use menu system to select the more advanced functions, change units etc.
