Abstract
Abstract An apparatus and method for indicating the temperature of the environment into which a reaction vessel may be placed is provided by a container holding a thermally efficient fluid. The container has an identical external configuration substantially identical to the reaction vessel and is adapted to be positioned within the environment in place of the reaction vessel. A temperature sensor in thermal communication with the thermally efficient fluid provides an electrical parameter indicating the temperature of such fluid and thus the environment of the reaction vessel.
