* Specifications are based on measurements made with cylinder gases using a flow rate of 500 ml/min and are valid at 20°C, 50 %RH and 1013 mBar using Honeywell recommended circuitry. Performance characteristics outline the performance of sensors supplied within the first three months. Output signal can drift below the lower limit over time.

** Linear through the concentration range across the whole operational environment range.
