The 21852 is offered for customers who order a new data logger and, in addition to the Campbell Scientific calibration over the selected temperature range, require calibration verification from a certifying body that is accredited to the ISO 17025 standards. A paper certificate of the ISO/IEC 17025 accredited calibration is provided.
Please note that this service increases the delivery time of a new data logger.
21852提供给那些希望从可信赖的校准实验室获得校准认证的用户。我们数据采集器中的很多种都支持这项业务（见兼容性）。请注意此项服务增加了新的或被维修的数据采集器的发运时间。
新的数据采集器
如果对一个新的数据采集器订购了21852，Campbell Scientific生产并校准数据采集器，再把它送到位于犹他州盐湖城的Simco Electronics；Simco收到数据采集器后，会以A2LA/NVLAP标准实施校准认证。Simco还提供校准证书。
已经使用过的数据采集器
如果在数据采集器的返修中订购了21852，Campbell Scientific的维护部门会修理数据采集器并进行校准，再把它送到Simco；Simco收到数据采集器后，会以A2LA/NVLAP标准实施校准认证。Simco还提供校准证书。
