during measurements.

I

NTERFERENCE

Exposure to high concentrations of sulfide should be avoided as it
can affect the sensitivity of the nitrous oxide microsensor.

Nitric Oxide (NO) is interfering the N

2

O sensor signal.

CO2 in mM concentrations may affect the zero signal of the sensor.

On suspicion of sensor damage, repeat calibration and consult
‘Trouble-shooting’.
