红外温度校准仪
详细信息
| 可快速校准多种红外测温仪。 36mm 直径的测试目标区域在保持长期稳定性，很高的精度的同时，具有很快的加热速度，固定的发射率设定为0.96。在需要更高精度的场合中，或者进行重新校准时，可以将一个JOFRA STS-103B 3mm 的外接标准传感器放在测试目标区表面下方来提高精度。 适应于要求快速校准的场合，仅重1.7kg ,可携带到现场。操作简单，具有自动步进功能，带稳定指示器，不锈钢外壳坚固耐用。  具有多种实用功能： • 使用上下箭头轻松设定温度。 • 稳定指示器提示校准仪已进入稳定状态。 • 自动步进功能提高校准效率。 • 温度设定功能保护被校准探头，避免超过适用温度。 • 重新校准方便快捷，仅需要标准传感器，无需软件。 • 随机带简单易用的校准软件JOFRACAL。 • 随机带JOFRA IR-LAB 计算软件可以计算不同的发射率引起的温度偏差。 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.
