Limited Warranty
Lafayette Instrument Company warrants equipment manufactured by the
company to be free of defects in material and workmanship for a period of one
year from the date of shipment, except as provided hereinafter. The original
manufacturer’s warranty will be honored by Lafayette Instrument for items
not manufactured by Lafayette Instrument Company, i.e. resell items. This
assumes normal usage under commonly accepted operating parameters and
excludes consumable products.
Warranty period for repairs or used instrumentation purchased from Lafayette
Instrument is 90 days. Lafayette Instrument Company agrees either to
repair or replace, at its sole option and free of part charges to the customer,
instrumentation which, under proper and normal conditions of use, proves to be
defective within the warranty period. Warranty for any parts of such repaired
or replaced instrumentation shall be covered under the same limited warranty
and shall have a warranty period of 90 days from the date of shipment or the
remainder of the original warranty period whichever is greater. This warranty
and remedy are given expressly and in lieu of all other warranties, expressed or
implied, of merchantability or tness for a particular purpose and constitutes
the only warranty made by Lafayette Instrument Company.
Lafayette Instrument Company neither assumes nor authorizes any person
to assume for it any other liability in connection with the sale, installation,
service or use of its instrumentation. Lafayette Instrument Company shall
have no liability whatsoever for special, consequential, or punitive damages
of any kind from any cause arising out of the sale, installation, service or use
of its instrumentation.
All products manufactured by Lafayette Instrument Company are tested
and inspected prior to shipment. Upon prompt notication by the Customer,
Lafayette Instrument Company will correct any defect in warranted equipment
of its manufacture either, at its option, by return of the item to the factory, or
shipment of a repaired or replacement part. Lafayette Instrument Company
will not be obliged, however, to replace or repair any piece of equipment,
which has been abused, improperly installed, altered, damaged, or repaired by
others. Defects in equipment do not include decomposition, wear, or damage by
chemical action or corrosion, or damage incurred during shipment.
Limited Obligations Covered by this Warranty
1. In the case of instruments not of Lafayette Instrument Company
manufacture, the original manufacturer’s warranty applies.
2. Shipping charges under warranty are covered only in one direction. The
customer is responsible for shipping charges to the factory if return of
the part is required.
3. This warranty does not cover damage to components due to improper
installation or use by the customer.
4. Consumable and or expendable items, including but not limited to
electrodes, lights, batteries, fuses, O-rings, gaskets, and tubing, are
excluded from warranty.
7. Failure by the customer to perform normal and reasonable
maintenance on instruments will void warranty claims.
8. If the original invoice for the instrument is issued to a company that
is not the company of the end user, and not an authorized Lafayette
Instrument Company distributor, then all requests for warranty must
be processed through the company that sold the product to the end
user, and not directly to Lafayette Instrument Company.
