Calibration
Under environmental radiation, the counter tube is not subject to fatigue and, therefore, will not re-
quire re-calibration. However, if the user holds ISO certication, periodical calibration is mandatory.
For this purpose, we offer the following service:
Testing is sub-contracted to an assembly operation, which tests it for 72 hours against a master.
The master is calibrated against a gauged reference source (Cs-137). A data log is then generated.
To the best of our knowledge, this record is accepted as compliant by ISO auditors without excepti-
on.
Currently, this costs 50 Euro before sales taxes.
