Crompton Instruments has been making analog meters since 1881. That’s over 140 years of instrumentation that has served the industry faithfully despite its inherent limitations. Good help may be hard to find, but let’s get real here—it’s 2019, wouldn’t you say it’s about time for a meter made in this century?
At Otek we absolutely believe it is time indeed, and that’s why we molded our patented (and industry first!) loop-power technology to meters that measure up to the changing demands and needs of the 21st century nuclear industry. We call it The New Technology Series, and with obsolescence rising fast all around us, there has never been a better time to plan for the future by unplugging your analogs and plugging in Otek!
For the Crompton 007 series in particular, we proudly offer our NTM-N, NTM-M, and Solid State Analog Meter (SSAM-N) models respectively, as 100% Form, Fit, and Function replacements for the Crompton 007 for Class 1E safety related and nuclear qualified applications, including Mil-Spec 461, 167-1, 810F, 901C, and IEEE-344. Additionally the NTM-N and NTM-M are both Cyber Security Compliant, while the SSAM-N is Cyber Security Exempt due to a lack of all critical digital assets (saves you time and money!).
All three models come with our patented input signal fail alarm, fully customizable colors, and our lifetime warranty. All the models are 100% loop-powered—just like analog meters, only with our 21st century technology!
As you can see, with such diversity in our products Otek really strives to make sure each and every one of our customers is satisfied. That’s why if you’re considering analog replacements, give us a call at (520) 748-7900 or shoot us an email at sales@otekcorp.com.
Remember—we customize our technology to meet your needs!
