Five reasons to replace mercury thermometers
4. 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
accurately represents the actual
measured temperature.
5. 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 requirements—which is
only 7 cm (2.8 in) in the case of
the 1551A Ex.
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.
2. 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.
3. 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.
