All performance specifications are based upon the following environment conditions: 20 ℃, 50% relative humidity and 1 atmospheric pressure (100 kPa or ambient pressure). 2. Recommend calibration with target gas. If calibration with a cross sensitivity gas, we cannot ensure the accuracy of calibration and measurement. 3. The cross sensitivity may fluctuate between +/- 30% and may differ from batch to batch or from sensor’s life time. 4. The cross sensitivities are including but not limited to the above gases. It may also respond to other gases.
