This unique set combination of the Kilner thermometer and lid lifter are essential tools for preserving and pickling. The thermometer provides accurate measurements in centigrade., wth a handy clip that safely secures the thermometer onto the side of a preserving pan. The lid lifter incorporates a small, strong magnet at the end of the rod which can be used to remove discs and screw bands safely from boiling water during the sterilisation process and then to add the disc and screw bands to the glass jar once filled.
