Hello Terry,

If the HDC3020 is left at 99% RH for 8 hours there could be a chance the accuracy may start to creep over 3.5% RH. The chance of this occuring would grow the longer the device is left at this setpoint.

Regards,

Harry

Hi, Harry,

Have we ever test the data that keep it in 99% PH for long time?

Or is there a document that can show our such performance even is worth than 3.5% but still better than other supplier?

Thanks.
