    UV Measurement Products

Nov. 24 2020 press release: Counterfeiting of EIT Instruments in China.

EIT's first UV measurement product was developed and sold in 1984. 

Today, EIT's UV measurement solutions include instruments and sensors for UV LED & UV Broadband (arc, microwave, spot) sources.

EIT instruments are used in industrial UV curing applications including medical, printing, wood, aerospace, automotive, fiber optic, converting  and electronics.

  • EIT designs and manufactures in house high-quality, robust, and highly accurate industrial UV measurement instruments
  • We have a wide selection of product choices for UV LED and UV broadband (arc, microwave, spot) sources
  • EIT instruments allow communication between end users, formulators, UV source suppliers and equipment integrators
  • EIT has an extensive worldwide distribution network that offers prompt technical support and sales 
  • Service is available from EIT or through one of our EIT Authorized Service Centers
  • All EIT calibrated instruments are NIST traceable

UV LED Measurement

UV energy for industrial applications has historically been generated by mercury/mercury-additive based lamps using arc or microwave technology. UV generated by mercury sources is "broad band" with output across the ultraviolet, visible and infrared spectrum.  UV LED sources generate UV in a relatively narrow band. Power levels, spectral choices available, LED features and the form factor of the equipment have allowed LEDs to be used in new UV applications and in some cases be used in place of broadband UV technology.

UV Broadband Measurement

EIT Products designed to measure UV broadband (mercury/mercury additive) sources are in this section. EIT radiometers are available in single and four-band configurations in different dynamic ranges.

EIT Online measurement solutions provide continuous monitoring of UV systems to detect UV curing problems in real-time. They can be used with an EIT radiometer or by themselves in locations with limited space.

Care and Cleaning

EIT radiometers are electro-optical instruments designed to measure UV in a wide variety of lab and industrial environments.  Whether the instruments are used in a clean-room or on dust filled wood production line, EIT radiometers perform better when they are handled and cleaned using the guidelines below.

 

Use common sense and handle your EIT instrument with care. If it stops (accidently dropped, stuck in equipment, contaminated by coating) working, it should be sent to EIT for evaluation using a Service Request Form. Proper cleaning of the outer optics is key to having your EIT instrument perform as designed between service intervals.  Review the attached guidelines and/or watch the brief instructional videos which can be found below.

 

If you elect to use a commercial wipe, make sure they are free of detergents like the EIT Instrument Wipes. The guidelines here are general and any specific questions should be directed to EIT (uv@eit.com).
