The RTD sensor of the Fle 1151A Ex 'Stik' Thermometer is housed in a rugged stainless steel sheath - you no longer have to worry about breaking a mercury-in-glass thermometer and the subsequent clean up.

Note: Model number appended with a -9, -12, -20 indicates probe sheath length in inches. All probe diameters are 6.35 mm with the exception of the 1551A-9, which is 4.8 mm diameter.
Finally, a digital substitute for your mercury-in-glass thermometers! Accurate and repeatable to ± 0.05 °C over its full range, the Fluke 1551A '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.
The large backlit LCD display on the Fluke 1551A Ex rotates 90° degrees making it easy to read from any angle. A user-configurable stability/trend indicator lets you know when your temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to three hundred hours. A low-battery indicator and stop-measure function prevent erroneous measurements from being made due to low battery life.
The sensor of the Fluke 1551A Ex requires a minimum immersion depth of only seven centimeters (2.8 inches), with no appreciable effect on the measured temperature due to heat loss through stem conduction.
