Welcome to choose our instruments. This product is
a specialize micro-computer temperature controller for
refrigerator and freezer. The panel in English takes it
easy to use and avoid entering confusing menu repre-
sents the parameter setting. Our sensor is precisely ma-
de and sealed. It is moisture proof, therefore its perfor-
mances are more stable and reliable.
