Full Service EMC/EMI and Environmental Testing

NTS Longmont is a full-service testing laboratory offering EMI / EMC emissions and immunity testing as well as environmental testing capabilities including thermal cycling, acceleration, classical shock and vibration testing.


NTS Longmont has over twenty-years experience serving the needs of customers in Colorado and beyond. With the ability to design for a broad range of testing environments, NTS Longmont routinely solves problems for clients and has provided up-front design and retrofit for products to be used in medical, residential, commercial, industrial and space environments.Our new environmental and dynamic testing capabilities give our clients a single-source to meet the dynamic and environmental requirements of MIL-STD-810, MIL-STD-461, RTCA DO-160 and others.

EMI / EMC Testing Services

10 Meter EMI Chamber

  • CBTL Certified Testing - NTS is one of the few CB Testing Laboratories (CBTLs) for electromagnetic compatibility in the United States. We can accommodate CB Scheme EMC testing on medical products for world-wide compliance. Our scope includes 2nd, 3rd, and 4th editions of IEC 60601-1-2.
  • Commercial EMC Testing - NTS has the ability to test a wide range of commercial products, from battery-powered, handheld meters to electrosurgical generators. Full compliance emissions and immunity testing is performed under one roof.
  • Medical EMC Testing - NTS tests electronic devices used in a hospital environment or other medical applications including life support equipment, generators, and x-ray equipment as well as smaller devices such as pulse oximeters.
  • Military and Aerospace EMC Testing - NTS Longmont has provided EMC testing services on a number of programs, including the International Space Station and the C-17 Globemaster. MIL-STD testing, trouble-shooting and mitigation and design has been performed on actuators, CCUs, Launch, IR and UV cameras, and more.
  • Prescan & Mitigation - NTS provides engineering-level EMC immunity and emission testing for all tests that will be required for full compliance. Pre-scans are abbreviated tests which aim to identify potential problem areas earlier in the design cycle.
  • Pre-scan Emissions Testing - Enables clients to determine whether or not a compliance problem exists long before it can impact time to market. Pre-scan services have found that we offer an excellent environment for them to trouble-shooting EMC issues.
  • Two fully accredited 10-meter chambers - NTS Longmont boasts two fully accredited 10-meter chambers for our emissions testing, giving clients the advantage of more reliable data while saving them time and money.
