Warranty
This equipment is sold subject to the mutual agreement that it is warranted by us free from
defects of material and of construction, and that our liability shall be limited to replacing or
repairing at our factory (without charge, except for transportation), or at customer plant at our
option, any material or construction in which defects become apparent within one year from the
date of shipment, except in cases where quotations or acknowledgements provide for a shorter
period. Components manufactured by others bear the warranty of their manufacturer. This
warranty does not cover defects caused by wear, accident, misuse, neglect or repairs other than
those performed by Teledyne or an authorized service center. We assume no liability for direct
or indirect damages of any kind and the purchaser by the acceptance of the equipment will
assume all liability for any damage which may result from its use or misuse.
We reserve the right to employ any suitable material in the manufacture of our apparatus, and
to make any alterations in the dimensions, shape or weight of any parts, in so far as such
alterations do not adversely affect our warranty.
Important Notice
This instrument provides measurement readings to its user, and serves as a tool by which valuable
data can be gathered. The information provided by the instrument may assist the user in
eliminating potential hazards caused by his process; however, it is essential that all personnel
involved in the use of the instrument or its interface, with the process being measured, be properly
trained in the process itself, as well as all instrumentation related to it.
The safety of personnel is ultimately the responsibility of those who control process conditions.
While this instrument may be able to provide early warning of imminent danger, it has no
control over process conditions, and it can be misused. In particular, any alarm or control
systems installed must be tested and understood, both as to how they operate and as to how
they can be defeated. Any safeguards required such as locks, labels, or redundancy, must be
provided by the user or specifically requested of Teledyne at the time the order is placed.
Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser is
responsible for the training of personnel, for providing hazard warning methods and
instrumentation per the appropriate standards, and for ensuring that hazard warning devices and
instrumentation are maintained and operated properly.
Teledyne Analytical Instruments, the manufacturer of this instrument, cannot accept
responsibility for conditions beyond its knowledge and control. No statement expressed or
implied by this document or any information disseminated by the manufacturer or its agents, is
to be construed as a warranty of adequate safety control under the user’s process conditions.
