Handling Tips

Storage of GRAETZ radiation measuring instruments

Please observe the storage temperatures given in the respective operation manual. The place of storage shall be dry. If the instrument is stored for a longer time, please remove the batteries to avoid damage by leaking batteries.

The instrument shall be operated at least once a year (for example for one hour).

Cleaning the GRAETZ radiation measuring instruments

In case an instrument became wet during use in rain or snow, it has to be dried at room temperature. Dirty parts have to be cleaned with a moist cloth and dried afterwards.

Contaminated devices have to be cleaned with a soft brush by using lukewarm decontamination solvent (0,5 % decontamination solvent, alkaline detergent dissolved in water) or by using a customary mild detergent.

Please do not use organic solvents or aggressive cleaning agents.

After cleaning please check whether the instrument is free of contamination (current limit values acc. to your domestic radiation protection regulation).

Disposal of old GRAETZ Measuring Instruments

Old electric/electronic devices often still contain valuable materials, but also harmful materials which have been necessary for their function.

PLEASE NOTE: Disused devices do not belong to residual waste!

GRAETZ Strahlungsmeßtechnik GmbH takes your old GRAETZ device back free of charge and cares for its skilled disposal. This offer applies to all instruments supplied since August 2005.
