Product Description
7ETO CiTiceL Ethylene Oxide Sensor (C2H4O Sensor) Key Features & Benefits:
• Robust, industry standard 7-Series packaging
• Compact Size
7ETO CiTiceL Ethylene Oxide Sensor (C2H4O Sensor) Technical Specifications
* Specifications are valid at 20°C, 50% RH and 1013 mBar, using City Technology recommended circuitry. Performance characteristics outline the performance of sensors supplied within the first 3 months. Output signal can drift below the lower limit over time.
PART NUMBERS
7ETO is supplied without bias board. If a bias board is required with the sensor, 7BETO should be ordered.
