产品描述
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 (?") BSP. Common applications include food and drink, pulp and paper, chemical, sanitation, water and wastewater treatments.
