MRU GmbH, D-74172 Neckarsulm
The most important safety details are clearly marked with an attention sign.
1.4. Safety Information
The following safety procedures must to be followed at all times. They are a significant and
essential part of this manual. Failure to follow safety procedures can result in the loss of your
warranty claims.
Safety regulations
The analyzer may only be used as indicated in this manual. Our analyzers are checked
according to the following regulations:
VDE 0411 (EN61010) and DIN VDE 0701 before they leave the MRU GmbH factory.
MRU technical products are designed and manufactured according to DIN 31000/ VDE 1000
and UVV = VBG 4 of the professional guilds for fine mechanics and electrical engineering.
MRU GmbH assures that the analyzer complies to the essential requirements of the legal
regulations of the member states of the electro-magnetic compatibility (89/336/EWG) and to the
low-voltage regulations (3/23/EWG).
Specific safety regulations
Use only the battery charger supplied with the analyzer for this instrument.
No part of the analyzer, including the metal probe tube and all other metal parts & accessories
are to be used as electric conductors.
The analyzer is not to be used in or under water.
The analyzer is not to be placed near or directly exposed to open fire or heat.
The specified probe temperature range is not to be exceeded, as the probe, temperature
sensory mechanism and sensor could be damaged or destroyed.
The analyzer shall void dropping.
Attention:
Caution: Moisture, being pumped out of the condensates trap can be slightly acidic.
In case of skin contact IMMEDIATELY: clean affected parts of the body.
Avoid getting liquid in eyes.
Please carefully clean all parts that come into contact with the condensates.
After measurement, vent the analyzer with ambient air and allow the probe to cool.
A hot probe could cause burns or ignite flammable material.
Electrochemical sensors are by their operating principle not only sensitive to the gas they are
intended for, but for other gases as well. This cross sensitivity is compensated by MRU for the
typical application of flue gas analysis. However, unusual high concentration levels of single gas
components might lead to a reduced measurement accuracy of other gas components and to a
temporary change of the sensitivity of sensors, which may require several hours recovery time.
Especially concentration levels as high as several % for single gas components may affect the
measurement of other gas components at ppm level.
Those applications need to be discussed with MRU in detail.
