O2-A1 Alphasense 25% 1 Year Oxygen Smart EC Sensor

The O2-A1 Alphasense Oxygen sensor is designed to provide engineers, scientists and students an accurate and reliable way to measure up to 25% oxygen levels by volume. This sensor is a low cost, industrial safe, oxygen module designed to last one year. Features Electrochemical Sensor measures up to 25% Oxygen Smart EC board adds Barometric Pressure, Temperature and % Relative Humidity Sensors Smart EC Board Adds Serial UART Output Smart EC board Adds RS485 with Optional RS485 Cable Easy Integration; Compact & Low Power Models O2-A1 Sensor Only – Sensor only.  Unlike partial pressure oxygen sensors, they have good pressure and temperature dependence, making them the best choice in safety applications. Specifications Measurement Range: 0-20.9% oxygen Output: 80-120 uA @ 20.9% O2 Response Time: < 15 sec. t90 (s) from 20.9% to 0% O2 Linearity: 0.6% O2 deviation @ 10% O2 Output drift: < 1% change @ 3 months Operating life: > 24 months until 85% original Output of 20.9%
