Product Identity
COS41-2S is identified as the Oxymax COS41 dissolved oxygen sensor. Keep the full Endress+Hauser order number in the inquiry because nearby codes can represent a different electronic, mechanical, communication, approval, or calibration arrangement.
Oxygen Measurement File
This new article treats the item as water and wastewater oxygen measurement. Before purchase, verify membrane condition, electrolyte, flow conditions, temperature, calibration, and transmitter compatibility. Also record the installed tag, quantity, required date, destination, and the reason for replacement. These details help engineering and purchasing review the same scope.
Installation And Verification
Follow the manufacturer instructions and site safety procedure. Confirm isolation, wiring, grounding, seals, orientation, and environmental protection as applicable. After installation, prove device identity, output behavior, alarms, communication, and the normal process response. Save the final parameters and test result.
Stock, Price, And Delivery
Send HKXY Instruments the application and a clear image of the COS41-2S label. We can check the exact code, current stock, price, lead time, packing, and export documents. Use the official Endress Hauser reference as the technical starting point.
