High humidity is often signs of a leak- the SUNA V2 is sealed at the factory and is not meant to be opened outside of service, and an internal desiccant should prevent any moisture left over after assembly from affecting the electronics. In the case that your self test generated by UCI reports back a humidity higher than 30%, or a steady upwards trend over the course of your deployment.
As to the effects of high humidity, it is likely to cause:
– condensation to form on the inner surface of the optics window, under certain ambient conditions. This dramatically impacts the optics and will prevent you from collecting reasonable data.
– corrosion on internal connections and electronics boards, stressing the lamp function and spectrometer. Intense corrosion will lead to equipment failure.
It is difficult to know the time-frame under which the humidity conditions will affect the instrument, so, we recommend getting the SUNA serviced as soon as the humidity reaches about 30%. If you notice any concerning trends, reach out to the support team for recommendations.
