450ATT ReviewOur lab has replaced all previous thermometers with this model. Due to the simplicity in combination with accuracy, it is perfect for us. We purchased the 450ATT for T-type only use. Only issue ever experienced is when changing the battery, having to solder the wire back into place as they are delicate and pop off easily.
