The Best Alternative To Mercury Thermometers

In order to minimize sensor drift, the probe should always be protected from mechanical shock.
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.
Five reasons to replace mercury thermometers
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 isnt 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 isnt 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.
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 doesnt require that you match calibration conditions to achieve an accurate measurement. Youre only required to meet the minimum immersion requirementswhich is only seven centimeters (2.8 inches) in the case of the 1551A Ex.
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 youthe displayed temperature accurately represents the actual measured temperature.
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.
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 thermometersthis seems to be a growing trend.

Whats Wrong with My Reference Thermometer?

Industrial reference thermometers available on the market today, such as mercury-in-glass thermometers (or ASTM thermometers") 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 industrial 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 reference thermometer.

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 measurementsespecially 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.

Thermometer Probe and Digital Readout Combined Into One Unit

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 accurately calibrate the Stik Thermometer. Data logging to internal memory of up to 10,000 time-stamped measurements is optionally available.
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 year
