The invention relates to a recorder tool and particularly relates to a recorder for storage temperature change times. A recorder casing (13) is configured with a circular tube (2) which is internally provided with a piston (12), one end of the piston (12) is an enclosed chamber for working medium injection, the other end of the piston (12) projects out of a push rod (11), the push rod (11) is provided with a falling ball hole (10) of which a diameter corresponds to counting balls (9), the piston (12) and the push rod (11) do reciprocating motion at three positions of a first counting ball storage chamber (15), an outlet of a counting ball lower ball pipe (4) and a second counting ball storage chamber (8), repeated change times of a storage object at certain critical temperature during a storage or transportation period can be conveniently and visually observed and acquired by checking the number of the counting balls in the counting ball storage chambers, or repeated change times within an interval temperature scope can be acquired. The recorder is advantaged in that the recorder has properties of simple structure, low cost and reliable operation, can conveniently and directly acquire the storage temperature change times, has strong social benefits and has great market popularization and application prospects.
