The extra “LAZY HAND” (Ancillary pointer), is held by a magnetic clutch at the highest or lowest temperature reached in a given period. Designed for use where space is limited. A distinction of their sensing element is that it comes in virtual contact with the heat source and thus provides a fast readout.

Will hold calibration indefinitely unless mishandled. Can stand a temperature at least 50% beyond rating . Dial face and graduations are fired ceramic on stainless steel.
