All products manufactured by Apogee Instruments are warranted to be free from defects in materials and craftsmanship 
for a period of four (4) years from the date of shipment from our factory. To be considered for warranty coverage an 
item must be evaluated by Apogee.  

Products not manufactured by Apogee (spectroradiometers, chlorophyll content meters, EE08-SS probes) are covered 
for a period of one (1) year.  

What is Not Covered 
The customer is responsible for all costs associated with the removal, reinstallation, and shipping of suspected warranty 
items to our factory.  

The warranty does not cover equipment that has been damaged due to the following conditions:  

1. Improper installation or abuse.

3. Natural occurrences such as lightning, fire, etc.  

4. Unauthorized modification. 

5. Improper or unauthorized repair. 

Please note that nominal accuracy drift is normal over time. Routine recalibration of sensors/meters is considered part of 
proper maintenance and is not covered under warranty.  

Who is Covered 
This warranty covers the original purchaser of the product or other party who may own it during the warranty period.
