A temperature recorder which produces a continuous graphic record, scribed on a removable tape, of the temperature existing in an enclosure (such as a refrigerated railroad car) during a given period of time (e.g., the transit time of such a railroad car). The present temperature recorder-which is a modification, in disposable form, of the recorder for like purpose shown in U.S. Pat. No. 3,826,140, dated July 30, 1974- comprises, in a sealed case, a slow travelling tape which spans between a tape feed spool an a spring-driven tape take-up spool; there being a temperature-responsive device which scribes-in terms of temperature in relation to time-on the tape as it so travels, and means to regulate the speed of travel of said tape.
