Which of the following most accurately describes the problem?

T'HE need for close temperature control I on refrigerated vehicles has led to the development by the Partlow Corporation, New York, of an improved thermostat. It is now available in the U.K. through Corfield Industrial Controls, Ltd., 6 John Dalton Street, Manchester, 2, and can be supplied incorporated in a recording instrument to provide a record of the temperature during transport.

It is an electro-mechanical indicating instrument incorporating three switches for actuation in sequence of four different stages of cooling or heating. One or two auxiliary switches can be provided to change the cooling-heating cycles when required.

Power for the switches is supplied by a thermal element located in the refrigerated chamber and connected to the control body by a capillary tube. As chamber temperatures change the control switches are actuated in sequence. The instrument has a scale with an overall range of —30' F. to 170° F., calibrated in Fahrenheit only.
