Is the FLXA402 able to power the Hamilton DO sensors: Visiferm and DO70G?

Yes, the FLXA402 can directly power the Visiferm and DO70G. The modelcode selection for this is “D5”. It cannot be used as an analog sensor so MS code “D1” is not applicable for the Visiferm and the DO70G.
D1 is available for Oxygold G/B, Oxyferm and Oxysens.
