TC Temperature Calibrators–English
a. Remove all the easily flammable media from the vicinity of the calibrator.
b. Ensure that the calibrator cannot come in contact with easily flammable or explosive
media.
•
Operate the calibrator only in the temperature range permissible for the DUT.
•
Ensure that the DUT is held securely in the calibrator.
a. Use only suitable inserts.
b. When doing so, also ensure that the structural safety of the calibrator is retained.
2.4 Calibration Liquid Safety Instructions
Before using calibration liquids, read the entire safety data sheet thoroughly. Pay particular
attention to the information on the physical and chemical properties.
Only use calibration liquids that are suitable for the required temperature range and which are not
flammable.
Always wear safety goggles when handling calibration liquids. Druck recommends the following
calibration liquids:
2.4.1 Water
•
Only use distilled water, otherwise excessive limescale and soiling will build up in the
calibrator micro bath tank.
2.4.2 Silicone Oil
•
Use only the silicone oil recommended in Table
•
Always read the safety data sheet supplied with the silicone oil before using it.
•
Always ensure adequate ventilation when working with silicone oil, since hazardous
substances can be released.
•
Prevent silicone oil from coming into contact with your eyes.
•
Since silicone oil is hygroscopic, always use the transport cover to close the calibration bath
after use.
2.4.3 Mineral Oil
•
Druck supplies silicone oil with the calibrators.
•
Using mineral oil is possible, but must be done at your own risk. The danger and the risk
must be borne by the user and our warranty will be rendered null and void.
