Same Day Service: All qualifying analyzers received for recertification through UEi Service+ are returned the same business day, Guaranteed.*
Free Shipping: UEi Service+ offers free shipping both to and from our service center. When customers book their recertification, they receive a prepaid UPS Ground shipping label.
Standard Service


The C160 series combustion analyzers are designed and manufactured in our UK factory. Beyond a great product, we want to be sure your analyzer is working in peak condition for you. Returning your analyzer for annual recertification enables us to increase your standard 1-year warranty by 1 year up to 10 years from the date of purchase. Through UEI Service+, we’ve made the task of returning your analyzer as low cost, easy, and fast as possible. That’s UEi’s commitment to you.


Cal Now: UEi analyzers include a helpful “Cal-Now” message to alert you when it’s time to recertify. Occasionally, the message will appear early. If this happens, register your analyzer at www.ueitest.com/service then call our customer service professionals at 1-800-547-5740 and we’ll resolve the issue for you.

A UEi Service+ warranty includes:

UEi combustion analyzers are warrantied to be free from defects in materials and workmanship for one year from the date of purchase. The warranty does not cover batteries, fuses, probes, consumables, or (in our judgment) physical damage or misuse.

What If I Don’t Book Through ueitest.com/service?

If you have booked your service through an alternative channel besides ueitest.com/service, you will receive a 1-year warranty extension and a full inspection, but you will not receive free shipping or same day service.

What if I service my unit outside of the warranty period?

Customers who recertify their analyzer outside of the 12-month warranty period will receive a warranty extension, a full inspection and will be charged at standard service pricing. Next year, the analyzer will be eligible for UEi Service+ provided recertification is booked through www.ueitest.com/service within 12 months.

What if I Book Online Through Another Channel?

We are unable to administer 24-hour service or preferred pricing through our distribution channels. For this reason, we strongly encourage customers to book their service directly online at ueitest.com/service.

What if I have an older model?

If you have a legacy combustion analyzer (50, 70, 80, 120 or 150 series), we are unable to offer UEi Service+ due to the age and material cost of the product. We will soon be offering UEi Service+ Legacy for these products. Details coming soon.

Available to US customers only.

*We'll need 48 hours for analyzers with a NO (Nitric Oxide) sensor installed.
