Warranty / Service / Calibration


SARAD GmbH provides a general 24-month warranty for customers in the European Union countries and 12 months for customers outside of the EU. Since SARAD GmbH also distributes the products of other manufacturers; their warranty shall apply to those products. The warranty period begins with the receipt of the goods by the customer. We reserve the right of rectification.

Repair service

We offer a cost-effective repair service for our products. We repair your instruments within the warranty period and after. For items that we re-sell only, we will forward your repair request to the manufacturer directly. For the repairs please send your instrument to us:


Wiesbadener Straße 10,

01159 Dresden

Please contact us via the contact form on our website before sending in instruments for repair. After the end of the warranty, we will charge some fee for the initial check and estimate of cost depending on the type of instrument.

Calibration service

Now we perform calibrations of all measuring instruments by ISO and DKD standards. We calibrate each instrument from our product range, both new devices as well as older instruments.

Since December 2021 our Radon calibration lab is DAkkS-accredited according to DIN EN ISO/IEC 17025:2018 and performs all Radon calibrations according to their requirements. A standard calibration is performed at a radon concentration of 3 000 Bq/m³ with the prior determination of the background effect. A second calibration point at a radon concentration of 300 Bq/m³ is possible on demand and at additional cost. More information regarding 2nd-point radon calibration and the price you will find on the product page in the section "Accessories".  A separate calibration certificate is created for each calibration point.

All information regarding re-calibration or calibration of instruments that were purchased earlier as well as a calibration request form you will find here. If any questions regarding calibration occur or assistance is needed, please do not hesitate to contact us using the following e-mail address: calibration(at)sarad.de.  Our calibration team will be glad to provide you with all the detailed information. Please note, that we are calibrating all digital radon monitors, not only ours.

Recalibration of older instruments

The same as above. Moreover, we are able to recalibrate instruments of other manufacturers.
