Product Overview
The EC4-500-ETO is an industrial Ethylene Oxide (ETO) sensor designed for detecting ETO in various industrial environments. It offers a measurement range of 0-500 ppm with a T90 response time of 120 seconds. The sensor operates within a temperature range of -20C to +50C and a pressure range of 900 to 1100 mbar, with an operating humidity range of 15% to 90% RH. It is recommended for applications where ETO monitoring is critical. The sensor has an expected operating life of 24 months in air and features a long-term sensitivity drift of less than 2% signal per month.

Important Notes:
- Performance specifications are based upon environment conditions of +20C, 50% RH, and 1 atm (1013mBar).
- PCB sockets are recommended for sensor pin connection; soldering is to be avoided and will invalidate the warranty.
- Avoid exposure to high concentrations of solvent during storage, fitting, and operation. Use degreasing agents prior to fitting sensors on PCBs.
- Electrochemical gas sensors may fail to meet specifications without warning. For life safety applications, check sensor response to gas before use.
