pHionics Inc. warrants its instruments to be free from defect in material and workmanship under normal use for a period of twenty-four months from date of purchase by the initial owner (the warranty excludes the electrode for all products except the STs Series Conductivity electrode. The conductivity electrode does have a full 24 month warranty). Please test the unit before using it in your application. We cannot accept the return of a sensor or sensor/transmitter after application for reasons other than warranty. Nor do we warrant the sensor or sensor/transmitter for any specific application. Determination of application compatibility is the sole responsibility of the procurer. pH, ORP, dissolved oxygen, and similar electro-chemical electrodes are not warranted against failure. If the sensor or sensor/transmitter is stained or disfigured in such a manner as to preclude it from being sold as new — the unit cannot be accepted as a return and the procurer will remain responsible for any monies owed.

The sensor/transmitters are tested extensively during manufacturing and cannot be warranted against leaks once they leave the factory due to improper removal and insertion of sensor/electrode and cable assemblies.

Warranty does not cover defects caused by abuse or electrical damage. pHionics will not cover under warranty any instruments damaged during shipment to the factory improperly packed. Repair attempts by other than authorized service personnel will void warranty.

If within the warranty period, the equipment does not meet the specifications at time of purchase, pHionics shall correct any such defect or non-conformance by either repairing any defective part or parts that are returned to us, or by making available at your facility (via lowest freight rate) a repaired or replacement part, or by crediting your account, if we deem it appropriate.

Items returned for warranty repair must be prepaid and insured for shipment. Warranty claims are processed on the condition that prompt notification of a defect is given to pHionics within the warranty period. pHionics shall have the sole right to determine if in fact a warranty situation exists.

pHionics’ warranty does not cover travel, travel time, mileage, removal, reinstallation, or calibration expenses.

The foregoing warranty is exclusive and in lieu of all other warranties whether written, oral, or implied, and we make no warranty of merchantability or fitness for a particular purpose.

Our liability to you arising out of supplying of this equipment or its use whether based on warranty, contract or negligence shall not in any case exceed the cost of correcting defects in the equipment as herein provided and upon the expiration of the applicable warranty period as aforementioned, all such liability shall terminate. The foregoing shall constitute your sole remedy and our sole liability. In no event shall we be liable for special or consequential damages.
