For a reliable function and high measurement quality it is necessary to
inspect and service the analyser regularly.

recommends a regular bi-annual maintenance at a minimum, which must
carry by a qualified technician.
Apply personality safety equipment, against high H
concentrations before open the device.
Under special conditions the device can accumulate with toxic
gases.
► Measure the atmosphere, around the device, before
opening it.
