Abstract

A sensor 10 for producing a signal representative of the instantaneous amount of a substance in an environment e.g. hydrogen peroxide in a sterilization chamber, comprises a first element 18 for producing a first signal representative of the temperature T1 of the environment. The first element is isolated from the substance. A second element 12 includes a material which is capable of interacting with the substance to modify the temperature T2 sensed by the second element. The second element produces a second signal representative of the modified temperature such that the first and second signals are representative of the instantaneous amount of the concentrate in the environment. The sensor 10 may be used in a system for indicating the instantaneous amount of a substance in an environment or in a system for controlling the instantaneous amount of a substance in a chamber. <IMAGE>
