WARRANTY

NOVATECH  INSTRUMENTS  warrants  that  all  instruments  it  manufactures  are  free  from  defects

 

in 

material  and  workmanship  and  agrees  to  replace  or  repair  any  instrument  found  defective  during  a

 

period of one year from date of shipment to original purchaser.

This warranty is limited to replacing or repairing defective instruments that have been returned by

 

purchaser,  at  the  purchaser's  expense,  to  NOVATECH  INSTRUMENTS  and  that  have  not  been

 

subjected to misuse, neglect, improper installation, repair alteration or accident. NOVATECH

 

INSTRUMENTS shall have the sole right to final determination regarding the existence and cause

 

of a 

defect.

This warranty is in lieu of any other warranty, either expressed or implied, including but not limited to

 

any warranty of merchantability or fitness for a particular purpose. In no event shall seller be liable for

 

collateral or consequential damages. Some states do not allow limitations or exclusion of consequential

 

damages so this limitation may not apply to you.

All instruments manufactured by NOVATECH INSTRUMENTS should be inspected as soon as

 

they 

are  received  by  the  purchaser.  If  an  instrument  is  damaged  in  shipment  the  purchaser  should

supported with adequate shock absorbing material.

This  warranty  constitutes  the  full  understanding  between  NOVATECH  INSTRUMENTS  and  the

 

purchaser and no agreement extending or modifying it will be binding on NOVATECH

 

INSTRUMENTS  unless  made  in  writing  and  signed  by  an  authorized  official  of  NOVATECH
