You can adjust the CO2 measurement of GMP231 in 1 or 2 points.

  • 1-point adjustment is recommended if you are interested in maintaining a fixed CO2 level inside the chamber. For best result, use a calibration gas with a CO2 concentration that is close to the intended level.
  • 2-point adjustment is recommended if you typically measure a variable CO2 level.

Available adjustment functions depend on the interface you use to operate the GMP231. If you want to integrate the functionality into the incubator’s control system, the I2C interface and the Vaisala Industrial Protocol are recommended. If you want to compare the reading of the GMP231 to a reference instrument as adjust it accordingly, use an MI70 handheld indicator and a reference probe.
