A thermometer includes a probe portion having a central axis, an adjustment member secured to the probe portion in a manner preventing relative rotation thereof, and a dial portion which is rotatable relative to the probe portion about the central axis thereof for calibrating the thermometer. The adjustment member is a nut having lobes whereby torque can be applied to the adjustment member by hand for effecting relative turning movement of the probe portion and the dial portion without use of a turning tool.
