A thermometer management system comprising: a) one or more digital probes (13012a, 13012b, 13012c) that include a probe that senses and reacts to a temperature of an object to be measured, and that output a digital output which the probe output is digitized; b) a display temperature generator that inputs the digital output and generates a display temperature; c) management operation execution means that executes, according to a received predetermined command, a predetermined management operation that is associated with the command; d) an RFID tag that stores management data including the command and metadata, the metadata indicating an allowable temperature of the object to be measured or an allowable temperature change of the object to be measured; e) an RFID reader (1009, 13009, 13013) that transmits information received from the RFID tag to the management operation execution means; and f) an alarm that detects a temperature error and sounds an alarm according to an alarm operation mode, wherein the RFID reader (1009, 13009, 13013) receives the management data from the RFID tag by being triggered by the RFID tag approaching close to the RFID reader (1009, 13009, 13013) and transmits the management data to the management operation execution means, wherein the management operation execution means executes the management operation based on the command included in the management data, and wherein the management operation comprises execution of a switching function when the command indicates a switching of alarm operation mode, the switching function switching the alarm operation mode to a mode in which the temperature error is detected based on the allowable temperature or the allowable temperature change indicated by the metadata and sounding an alarm. a) one or more digital probes (13012a, 13012b, 13012c) that include a probe that senses and reacts to a temperature of an object to be measured, and that output a digital output which the probe output is digitized; b) a display temperature generator that inputs the digital output and generates a display temperature; c) management operation execution means that executes, according to a received predetermined command, a predetermined management operation that is associated with the command; d) an RFID tag that stores management data including the command and metadata, the metadata indicating an allowable temperature of the object to be measured or an allowable temperature change of the object to be measured; e) an RFID reader (1009, 13009, 13013) that transmits information received from the RFID tag to the management operation execution means; and f) an alarm that detects a temperature error and sounds an alarm according to an alarm operation mode, wherein the RFID reader (1009, 13009, 13013) receives the management data from the RFID tag by being triggered by the RFID tag approaching close to the RFID reader (1009, 13009, 13013) and transmits the management data to the management operation execution means, wherein the management operation execution means executes the management operation based on the command included in the management data, and wherein the management operation comprises execution of a switching function when the command indicates a switching of alarm operation mode, the switching function switching the alarm operation mode to a mode in which the temperature error is detected based on the allowable temperature or the allowable temperature change indicated by the metadata and sounding an alarm.
