Abstract
Abstract A portable system for measuring a condition, particularly temperature, and indicating this measurement at a remote location. A portable insulating and protective container adapted for use in extreme temperature environments, such as occasioned within a furnace or oven, houses a small transmitter. The transmitter is connected to a transducer responsive to the condition to produce a signal that is transmitted to a remote receiving and monitoring location.
