1551A / 1552A Ex "Stik" Thermometer Readout
Accurate, stable and durable, making it the best alternative to mercury thermometers and existing electronic thermometers
Finally, a digital substitute for your mercury-in-glass thermometers! Accurate and repeatable to +/- 0.05°C over its full range, the Fluke 1551A, Fluke 1552A “Stik Thermometer is the new “gold standard" of 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.
