Customer Service

EIT products are sold and supported by EIT and our worldwide network of Representatives and Distributors. EIT radiometers are subjected to challenging conditions (intense UV/Light/IR, temperature, coatings, mishandling), all of which can affect their reliability and performance.

EIT does not know how units will be used and cared for. Because of this, we recommend a service interval of 6 months. EIT instruments are best serviced by EIT or an EIT Authorized Service Center. Units returned to EIT for service should be sent with the Service Request Form. 

Print out the Service Request Form (Excel format), fill it in, print it, and return the form with your package. Be sure to include company information, contact phone number and email information.

All packages must be sent freight pre-paid, door-to-door. If the unit is sent from outside the U.S., please be sure to identify the package as “U.S. made goods, returned for service”. Also see Changes to Duty Free Return of EIT Instruments Sent to EIT (USA) for Service. You will be responsible for damage incurred from inadequate packaging. You are also responsible for insuring the unit during transportation to EIT.

Why Re-Calibrate Your Instrument

EIT radiometers are designed, manufactured, assembled, serviced, sold and supported by EIT's worldwide network of Representatives and Distributors. EIT radiometers are exposed to challenging conditions (intense UV/Light/IR, temperatue, coatings, mishandling), all of which can affect their reliability and the performance of your instrument. 

EIT Instruments are best serviced by EIT technicians and EIT Authorized Service Centers who follow the calibration procedure for each instrument. EIT technicians and or Authoized Service Centers have access EIT master units, calibration software and genuine factory optical components to keep your unit in excellent working condition for optimal performance.

Calibration is recommended every 6 months for all UV measurement radiometers except MicroCure. 

All calibrated UV instruments have NIST traceability.
