When you calibrate the [problem] infrared thermometer, calibration work when it easy to visually confirm whether or not the thermometer is properly oriented to the subject of the room temperature state, an environment in which to use the infrared thermometer was sudden change the simplicity. A toward the infrared sensor 3 of the infrared thermometer 1 to measure subject to the same temperature as the ambient temperature, when the switch is pressed for manual calibration means 15, two points for projecting the display means 6 light by changing the orientation of the infrared sensor 3 in the handheld as readable information during the point is located, a positive state in which the infrared sensor 3 is separated by a predetermined distance for calibrating the measurement subject to the same temperature as the ambient temperature It was configured against.FIELD 3【課題】赤外線体温計を校正するときに、室温状態の対象に対して体温計が適正に向いているか否かを目視確認し易くし、赤外線体温計を使用する環境が急変したときの校正作業を簡単にする。【解決手段】環境温度と同じ温度の測定対象に赤外線体温計1の赤外線センサ3を向けて、手動校正手段15のスイッチ押下をしたときに、表示手段6が投影する二点の光点の間に可読情報が位置するように赤外線センサ3の向きを手持ちで変更することで、環境温度と同じ温度の測定対象に対して赤外線センサ3が校正用の所定距離で離間した状態で正対する構成とした。【選択図】図3
