When necessary, you can apply pressure compensation to improve the measurement accuracy of the probe (probe software v.1.1.0 and later). The probe does not have on-board pressure measurement, but a pressure reading from an external source can be used as a setpoint value for compensation.

You can configure the pressure compensation parameters using Vaisala Insight software, Modbus configuration registers, Indigo200 transmitter, or Indigo80 handheld indicator.

By default, the pressure compensation is turned off. When the compensation is off, the probe uses the default compensation value (1013.25 hPa).

Pressure compensation affects the following parameters:
  • H2O2 concentration (ppm)
  • H2O concentration (ppm)
  • Relative saturation (%RS)
