1551A Ex and 1552A Ex "Stik" Thermometer

Thermometer probe and digital readout combined into one unit

The stainless steel probe and digital readout are fixed together and calibrated as a system. The accuracy specification

 is easy to understand since it includes all uncertainty components, including drift, for up to one year1. The large backlit 

LCD display 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. A simple three-point calibration function allows you to easily and

 accuray calibrate the “Stik" Thermometer. Data logging to internal memory of up to 10,000 time-stamped measurements

 is optionally available.

Why calibrate process temperature sensors?

Because temperature greatly 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. Finding a

 reference thermometer that is accurate, repeatable and robust, however, can be challenging.

What’s wrong with my reference thermometer?

Industrial reference thermometers available on the market today, such as mercury-in-glass thermometers (or “ASTM therm

ometers") and portable electronic thermometers are useful, but both come with inherent problems. Although accurate and 

repeatable, mercury thermometers are fragile. The risk of a mercury spill poses potential hazards to the environment and

 to the health of personnel. Many of the United States and European Union countries have already banned their use in ind

ustrial applications. Some organizations have replaced their mercury thermometers with more durable portable electronic 

thermometers, only to discover that the RTD probes lack the repeatability and dependability required of a legitimate ref

erence thermometer.

The best alternative to mercury thermometers

The Fluke “Stik" Thermometer is accurate, stable and durable, making it the best alternative to mercury thermometers and 

existing electronic thermometers. The thin-film RTD sensor incorporates the same characteristics of other premium reference 

thermometers designed by Hart Scientific, but it is more robust and less susceptible to drift. Accuracy and repeatability,

 however, are not sacrificed for improved durability.

Using a glass-stem mercury- or spirit-filled thermometer at different immersion depths, or at significantly different ambient

 temperatures from which it was calibrated, may require the application of emergent-stem corrections that can be tedious

 but necessary to calculate an accurate measurement. This isn’t required with the “Stik" Thermometer. The sensor of the 

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. Some digital thermometers can become less accurate

 when used outside a narrow range of ambient temperatures. This isn’t the case for the “Stik" Thermometer. Your 

measurement remains accurate in ambient temperatures from -10 degrees to 50 degrees celsius (14 degrees to 122 degrees

 fahrenheit). With a superior probe design combined with electronic functions that assist accurate measurement, the “Stik" 

Thermometer surpasses the capabilities of other digital thermometers and is the perfect substitute for your mercury

 thermometers. ¹In order to minimize sensor drift, the probe should always be protected from mechanical shock.

Five reasons to replace mercury thermometers

1. Since the “Stik" Thermometer does not contain mercury, it is not subject to government-imposed bans. 
   • Government agencies worldwide have either banned or are seeking to ban the use and transportation 
     • of industrial mercury thermometers—this seems to be a growing trend.
       • The stainless steel probe sheath of the “Stik" Thermometer is far more robust than the glass stem of a
         •  mercury thermometer and better suited for industrial environments. And since the “Stik" thermometer 
           • does not contain mercury, the risk of an accidental mercury spill is eliminated.
             • When considering cost of ownership, a digital thermometer is less expensive than a mercury thermometer. 
               • With a mercury thermometer, you either invest in equipment or you hire out to clean up after a mercury spill.
                 • Mercury thermometers cannot be adjusted after calibration. The actual temperature must be calculated by 
                   • applying corrections to the measured temperature. This costs time and is susceptible to calculation error. 
                     • A digital thermometer does the math for you—the displayed temperature accuray represents the actual 
                       • measured temperature.
                         • Emergent-stem corrections may also be required if the mercury thermometer is not used under the same
                           •  conditions under which it was calibrated. A digital thermometer doesn’t require that you match calibration 
                             • conditions to achieve an accurate measurement. You’re only required to meet the minimum immersion requir
                               • ements—which is only seven centimeters (2.8 inches) in the case of the 1551A Ex.
