Additional de-rating over Temperature:
±0.6 %/°C from calibration temperature
±0.6 %/°C < 20 °C
Long term drift < 2 % per month.
Maximum shift in arid or humid storage conditions*: ±0.6 % per day
(Reference storage test conditions:
50 °C, 15 % RH and 30 °C, 95 % RH)
*Note: After the CO calibration seal is removed and the Meter is stored for an extended period in arid or humid conditions,
verify that the sensor is within specification by applying a known concentration of gas using the calibration gas kit.
