_******[Approx. response time—ungrounded in water]_ ## **Long Life, Low Maintenance!** If your application operates at the punishing temperature of nearly 1204°C (2200°F), changing out failed thermocouples costs money in excessive maintenance, slows or cuts production, and can cause inconsistent product quality. **1204°C (2200°F) replace 17 of theirs in 52 days or just one of ours!** In life-cycle lab testing, the OMEGACLAD[®] XL sheathed, 0.125" Type K Probe operated continuously for 52 days at 1204°C (2200°F) while competitors’ 0.125" Inconel[®] 600 sheathed, Type K probes lasted 3 days. **†** In head-to-head tests, Super OMEGACLAD[®] XL Thermocouple probes consistently post the best performance results. Our innovative temperature sensors last upwards of 10 times or longer when compared to competitors’ Inconel[®] 600 sheathed probes of equal or larger diameters. Let OMEGA’s leading edge products help engineer _**your next innovation!**_ _**†** Results will vary on application and operating environment._ **A-43** **A** ## **Low Drift, Reliable Temperatures!** Super OMEGACLAD[®] XL’s low-drift characteristic ensures reliability of temperature readings longer than any other brand or sheath material. Within 15 weeks, Brands A, B, and C exhibited more than 8.3°C drift. At 25 weeks, OMEGACLAD[®] XL’s drift was less than 2.8°C.* **==> picture [227 x 124] intentionally omitted <==** **----- Start of picture text -----**
