 1. Details of model change

a) With more and more circuit components/parts in the probe no longer in production, it’s difficult to obtain the equivalent or compatible ones. We have decided to switch to a “New circuit board” that uses alternative/succeeding parts.
b) Regarding the water temperature circuit, we have reviewed the conversion formula which converts the resistance to the water temperature, and have adopted another conversion formula that has less variation.

 2. Software update

a) The windows software, that changes the conversion formula of water temperature, is in preparation.
b) Though the current software can also operate the new probe, there will be errors due to different conversion formula.
c) Though the errors are less than the resolution (0.01degC), have almost no effect. Please apply the updated software version.
