Fluke 1551A Ex/1552A Ex is the new “reference thermometer" for industrial temperature calibration. Whether working outdoors in environments where potentially explosive gases may be present or on the floor of a processing plant, the intrinsically-safe, battery operated, portable reference thermometer is designed to go where you work.

Super-Thermometers from Hart Scientific combine the accuracy of complex and expensive bridges with innovative features that simplify measurement processes and provide excellent value. Both Super-Thermometers are perfectly suited for calibrating SPRTs, PRTs, and thermistors. They are accurate enough for the primary lab and economical enough for the secondary lab.

Robust protection circuits prevent costly damage from operator error. Redesigned carrying handles make the 5522A easy to transport. The 5522A can also be fully automated with MET/CAL® Plus Calibration Management Software.
