Overview
The ORBISPHERE 3100 instrument is a self-contained portable analyzer, configured to make
oxygen concentration measurements in gaseous or liquid samples. Up to 5,760 measurement values
can be stored in memory and downloaded to a personal computer for further analysis.
The analyzer is available in 3 different versions (for 4mm, 6mm and 1/4 inch connections).
Installation
Carefully remove the analyzer and its accessories from the box and packing material, referring to the
packing list included to confirm that everything has been delivered. Please visually inspect the
analyzer for shipping damage. If anything is missing or damaged, contact the manufacturer or your
dealer immediately.
A thin protective film has been placed over the screen to protect it from damage during
transportation. For a clear view of the screen, this film must be peeled off before using the analyzer.
N O T I C E
A secondary more robust protective film has been factory installed over the screen to protect it from damage and
moisture ingress. Under no circumstances should this protection be removed. If it becomes damaged in any way,
please contact your local Hach Lange representative.
