Kipp & Zonen solar radiation measurement instruments comply with the most demanding international
standards. In order to maintain the specified performance of these instruments, Kipp & Zonen recommends
calibration of their instruments every two years.
This can be done at the Kipp & Zonen factory. Here, recalibration to the highest standards can be
performed at low cost. Recalibration can usually be performed within four weeks. If required, urgent
recalibration can be accomplished in three weeks or less (subject to scheduling restrictions).
Kipp & Zonen will confirm the duration of recalibration at all times. Please note that special quantity
recalibration discounts are available for instruments of the same type.
