The DOTX441 dissolved oxygen analyzer is
supplied in a compact cast aluminum case. SAE 323,
with low oxidation grade, anticorrosion treatment and
finished with electrostatic epoxy paint. The DOTX441 is
compact, light weight, rugged and IP-68 rated. The units include
local display, transmitter output and controller function all
programmed via a 3-button side panel with an easy self guided
menu. The DOTX441 can be mounted on a 51 mm (2") tube or flat
surface. Electrical connections are on the terminal bar located in
the back housing of the instrument with cable entrance through
two cable compression fittings of 13 mm (½") BSP. Common
applications include food and drink, pulp and paper, chemical,
sanitation, water and wastewater treatments.
