Product Details

Hamilton Dissolved Oxygen Electrode 10118255-1411

Product Overview

Product Name: VisiTherm RS485-ECS 325 H0
Order Number: 10118255-1411
Product Description: This is an optical dissolved oxygen (DO) sensor that integrates optoelectronic components and has complete measurement and self diagnostic capabilities. It adopts RS485 Modbus and ECS (electrochemical signal simulation) interfaces, making it an ideal choice for fermentation processes in the biopharmaceutical, biotechnology, and food and beverage industries.
Core advantages:

Optical measurement: No need to replace electrolyte or polarographic film, extremely low maintenance.
Dual interface: Supports both modern digital communication (RS485) and analog signals from traditional electrochemical electrodes (ECS), making it convenient for upgrading old devices.
No flow rate dependence: can accurately measure even in stationary liquids.
