Abstract
An apparatus is disclosed for indicating the boiling point of a fluid, the apparatus comprising: a control unit; and a probe suitable for insertion into the fluid. The probe comprising: a storage device; a heating arrangement suitable for heating the fluid; and a monitoring arrangement suitable for monitoring the temperature of the fluid heated by the heating arrangement. The control unit comprises a first connector and the probe comprises a second connector, the first connector and the second connector being attachable to form a communicative coupling between the probe and the control unit, and detachable to detach the probe from the control unit. The probe is configured to store on the storage device, probe calibration data for use by the control unit, and the control unit is configured to read the storage device to determine a calibration setting required for operation with said probe.
