This industrial automation component is supplied for enterprise procurement .Made-to-order and forward delivery are supported, with pricing quoted per inquiry.
To reduce sourcing risk, each order is handled individually with support for model confirmation, condition clarification, and lead time estimation before order placement. Clear quotation terms and consistent communication are provided to help partners manage expectations and complete transactions with confidence. Additional verification or clarification is available when required, supporting professional procurement and long-term cooperation.
COS61 adopts classic polarographic electrode design with a semi-permeable oxygen membrane to selectively capture dissolved oxygen molecules in aqueous media, eliminating cross-interference from most common water-borne contaminants. Integrated Memosens digital architecture converts raw electrode signals directly at the probe head, separating analog measurement circuits from transmission cables to resist EMI/RFI noise in industrial plant environments. The fully sealed IP68 submersible housing enables long-term permanent immersion without regular retrieval, while standardized 12 mm probe diameter supports pairing with E+H FCPS flow cells and CYH submersible holders.
