IF A MERCURY SPILL OCCURS . . .
FAQ (FREQUENTLY ASKED QUESTIONS)
Why use mercury?
Mercury (Hg) is a liquid metal with very stable performance charac-
teristics. As such, mercurial blood pressure devices remain the interna-
tionally recognized standard for accuracy. Because there are no moving
parts, springs, needles, casings, or other components that may become
defective or wear with age, mercury instruments are inherently the
most reliable and accurate. With minimal care and maintenance, these
instruments should last a lifetime.
What is so special about DIAGNOSTIX™ mercury instruments?
Our exclusive Safety First
™
system incorporates a number of distinctive
safety features that provide you with a level of protection no other
mercurial instrument can match.
Unbreakable graduated plastic cartridge tube
. Designed from space age
polymers, the tube exhibits remarkable performance stability. It will
not crack, craze, or shatter. Yellowing, a problem that plagued first
generation plastic tubes, is all but gone. Tolerances to .1mm assure
measurement repeatability.
Reservoir Locking Switch
secures the mercury safely in the reservoir
during routine maintenance, cleaning, or transport.
EZ Tube
™
System
simplifies the safe removal of the cartridge tube or
top cap filters for cleaning or maintenance without risking a spill.
