1551A Ex/1552A Ex Intrinsically
Safe “Stik” Thermometers
The best alternative to mercury thermometers
Finally, a digital substitute for your mercury-in-glass thermometers! Accurate and repeatable to ±0.05 °C over
its full range, the Fluke Calibration 1551A/1552A “Stik” Thermometer is the new “gold standard” of industrial
temperature calibration.
• Accuracy of ± 0.05 °C (±0.09 °F) over full range
• Intrinsically safe (ATEX and IECEx compliant)
• Two models to choose from (–50 to 160 °C or –80 to 300 °C)
• Display temperature in °C or °F
• 300-hour battery life
What’s wrong with my mercury thermometer?
Although mercury thermometers are accurate, they are also fragile and pose the risk of a mercury spill.
Many U.S. states and European Union countries have banned their use in industrial applications. The U.S.
Environmental Protection Agency has funded research to identify alternatives. But such initiatives have been
hampered by the lack of an electronic alternative that was intrinsically safe, repeatable and accurate. The Fluke
“Stik” Thermometers help solve this problem by providing the measurement accuracy, durability and safety
required in industries such as oil and gas production and petrochemicals—with no mercury hazard.
Why calibrate process
temperature sensors?
Because temperature effects the accuracy of a volumetric
measurement, process manufacturers of chemical, pharmaceutical,
food or petroleum products require accurate temperature
measurements—especially for processes where quality or custody
transfer are regulated by government agencies. Since all temperature
sensors are subject to drift with time, regular calibration or verification
against a reliable reference thermometer is required.
Thermometer probe and digital
readout combined into one unit
The stainless steel probe and digital readout of the Fluke 1551A
Ex/1552A Ex “Stik” Thermometers are fixed together and calibrated
as a system. Unlike competing products, the large backlit LCD display
rotates 90 degrees, making it easy to read from any angle. A user-
configurable stability/trend indicator lets the technician know when
the temperature is stable enough to record an accurate measurement.
A low-battery indicator and stop-measure function prevent erroneous
measurements from being made due to low battery life. Data logging
to internal memory of up to 10,000 time-stamped measurements is
optionally available.
