Maintenance
The
NGR
is maintenance-free. We recommend doing the following
regularly:
■
Checking the probe for contamination
■
Checking the screw connections and plug-in connections

Returning the level sensor
Declaration of no objection (contamination declaration in the event of service work)
Rinse off or clean removed devices before returning them in order to protect our employees and
the environment from dangers posed by residue from measured materials. Faulty devices can only
be examined when accompanied by a completed return form. A declaration of this type includes
information about all materials which have come into contact with the device, including those which
were used for testing purposes, operation, or cleaning. The return form is available at our Internet
site (www.
kobold
.com).

Disposal
Dispose of device components and packaging materials in compliance with applicable country-specif-
ic waste treatment and disposal regulations of the region of use.

Medium list
This medium list (from page 56) provides an overview of the DK values of liquids. Water-based
liquids always have a DK value of > 5, which allows
NGR
to be used easily. For DK values of < 5, a
coaxial tube or a metallic immersion tube/bypass is always required.
