How to determine and manage your calibration needs – four options explained

Caring about continuous accuracy – especially in the life science, manufacturing, and process industries – usually results in energy savings, better decision-making, and higher end-product quality. The more critical your application the more crucial regular calibration and adjustment becomes. In many cases regular calibration is required by local legislation and regulations or internal quality requirements; your customers most likely expect it, too.

The measurement technology and the parameter you are measuring are important considerations. Instrument manufacturers can usually give a general recommendation for a suitable calibration and maintenance interval. There may also be options for spot checking or field calibration that you can carry out yourself. In any case, in the long run it pays to commit to a trusted measurement instrument provider who invests in developing stable measurement technologies and who can help you with different types of calibration solutions throughout the product life cycle.
Let’s look at some of the calibration options.

1.Laboratory calibration是校准测量设备的最准确方法，因为影响校准的环境效应显着降低。使用Vaisala的校准实验室时，您可以选择获得认可的ISO/IEC 17025或标准ISO 9001校准；在这两种情况下，您都将获得具有可追溯的校准证书，并带有发现的结果，以证明准确性。在大多数情况下，如果需要，也可以在校准过程中修复设备。

2.使用手持设备的现场校准是一种快速简便的检查测量设备的方法，而无需将其从过程或过程区域中删除。现场校准需要一个工作标准作为参考，该标准可以是手持式测量仪器，可以校准该过程中安装的仪器。许多Vaisala客户会定期将其手持仪器归还给我们以进行快速实验室校准，然后管理其工艺仪器本身的校准。

3.基于盐溶液的现场校准器can be used to produce a multi-point calibration for measurement instruments in non-critical applications. Saturated salt solutions have a long tradition of relative humidity calibration because they make it relatively simple to create a set of fixed relative humidity points.

4.Field spot-checking使用手持式测量仪器是确定单元是否正常运行的快速简便方法。检查点检查不应与现场校准相混淆：在检查点检查时，稳定时间不像现场校准那样重要，因此这是一个更快的过程。现场检查可以被视为测量设备维护的良好补充，尤其是在关键应用中。

在Vaisala，我们认真对待测量准确性。我们的测量技术以其长期稳定性而闻名，我们帮助客户年复一年地保持这种稳定性。即使在最苛刻的测量条件下，通过合适的校准和维护选项也是可能的。
In addition to our comprehensive service center and on-site calibration services, we support our customers with their own field maintenance tasks with our wide selection of handheld measurement instruments that can be used for spot-checking and field calibration. Our Calibration Care Agreement enables continuous accuracy and regulatory compliance for handheld or any other instruments.
