Please be careful to ensure that Heyl indicators are used!
Using external indicators may result in considerable measurement
deviations or measurement errors. Damage caused by foreign parti-
cles in the area of the dosing pump, measuring chamber or valves is
also possible. This may invalidate the guarantee!
At Heyl, we always strive to ensure the consistently high quality of
our indicators. They are specially tailored to the requirements of our
measuring devices and guarantee flawless measurement results.
