Product Warranty

Apogee is continually improving the durability and reliability of our sensors. This ongoing process has reduced product failure to virtually negligible levels. As a result, Apogee Instruments is proud to announce that, as of September 1, 2013, all products we manufacture now carry a 4 year warranty. Registration is not required to activate the warranty. It begins when the product ships to you from our factory or from an authorized distributor.

All Apogee Instruments products have a four (4) year warranty against defects in materials and workmanship, except for the PS-Series Spectroradiometers, SS-110 and SS-120 Field Spectroradiometers, EE08 Humidity Probe, and the MC-100 Chlorophyll Concentration Meter, which carry a one (1) year warranty. Other third-party accessories, like batteries, carry the original manufacturer warranty.

4 Year Warranty

Some situations (but not all) that invalidate the warranty are:

  • The product has been subject to abuse, misuse, neglect, negligence, accident, improper testing, improper installation, improper storage, improper handling, or use contrary to instructions given by Apogee Instruments
  • The product has been altered by anyone except Apogee
  • The product has been operating outside of environmental specifications for the product
  • The product failed due to an extreme condition i.e. fire, flood, etc.
Please note, all precision sensors experience some accuracy drift over time. Our warranty does not cover the cost of recalibration as this is considered a routine maintenance issue. Please see our recalibration page for more details.

The bottom line is we want our customers to be happy. If you have any warranty questions with your product, please contact our tech support by email at or by phone at 435.245.8012.
