*1 The rest of the type name is omitted
*2 The operating temperature limit is determined by the allowable temperature limit of the sensor head contacts the measurement target. Note that the operatingtemperature limit is not the same as the allowable temperature limits of the grip, cable, and plug.
*3 Tolerance is evaluated using a dedicated Calibration System.
*4 The response time given for our temperature measuring probes is the time required to detect 99% of the true value when a soldering iron tip with sufficient thermal capacity is brought into contact with soldering iron thermometer.
*5 Can not evaluate because of special-application
*6 Please refer to page repair.
