| 可快速校準多種紅外測溫儀。 36mm 直徑的測試目標區(qū)域在保持長期穩(wěn)定性，很高的精度的同時，具有很快的加熱速度，固定的發(fā)射率設定為0.96。在需要更高精度的場合中，或者進行重新校準時，可以將一個JOFRA STS-103B 3mm 的外接標準傳感器放在測試目標區(qū)表面下方來提高精度。 適應于要求快速校準的場合，僅重1.7kg ,可攜帶到現(xiàn)場。操作簡單，具有自動步進功能，帶穩(wěn)定指示器，不銹鋼外殼堅固耐用。  具有多種實用功能： • 使用上下箭頭輕松設定溫度。 • 穩(wěn)定指示器提示校準儀已進入穩(wěn)定狀態(tài)。 • 自動步進功能提高校準效率。 • 溫度設定功能保護被校準探頭，避免超過適用溫度。 • 重新校準方便快捷，僅需要標準傳感器，無需軟件。 • 隨機帶簡單易用的校準軟件JOFRACAL。 • 隨機帶JOFRA IR-LAB 計算軟件可以計算不同的發(fā)射率引起的溫度偏差。 JOFRA STS-103 B It is not easy to make a good quality reference probe. The main requirement of a reference probe is stability. This means minimal drift as a function of operating time at the actual temperature. The less the probe drifts, the lower the measurement uncertainty.   Especially for the ETC-400 R calibrator JOFRA has designed a special 3 mm STS reference sensor, the STS-103 B. The sensor can be used as a reference sensor when a higher accuracy is required or for recalibration of the ETC-400 R. Due to the small immersion depth requirement of the sensor it can be placed under the surface of the target.
