Anions
Negatively charged ions.
See Solution Characteristics, pg. 42.
Algorithm A procedure for solving a mathematical problem.
See Temperature Compensation (Tempco) and
TDS Derivation, pg. 43.
FAC Free Available Chlorine. The amount of chlorine that
remains active in solution and is available for ongoing
disinfection. See Free Chlorine as an Indicator, pg. 47.
FC E FC E ™ directly measures ORP, the germ killing
property of chlorine and other oxidizing germicides.
It displays both the ORP reading (in mVDC) as well
as an equivalent free chlorine concentration (in
familiar ppm). For more information see FCE™:
Groundbreaking Measurement of Free Chlorine
Disinfecting Power in a Hand-Held Instrument on
the Myron L Company website.
Logarithm An arithmetic function. The inverse of an exponential
function. See pH Units, pg. 44.
ORP Oxidation-Reduction Potential or REDOX, See ORP/
Oxidation-Reduction Potential/REDOX, pg. 46.
REDOX An abbreviation for Reduction-Oxidation reactions.
Reaction This is the basic electrochemical process by which
chlorine destroys microbes by grabbing electrons from
the microbe’s proteins, denaturing the protein and
killing the organism. ORP directly measures the
strength of a solutions’ REDOX potential and,
therefore, sanitizing strength.
TDS Total Dissolved Solids or the Total Conductive Ions
in a solution. See Conductivity Conversion to
Total Dissolved Solids (TDS), pg. 41.
Tempco Temperature Compensation
See Temperature Compensation of Aqueous
Solutions, pg. 39.
User A mode of operation that allows the instrument user
(operator) to set a tempco and/or a TDS factor for
their specific solution type. See Temperature
Compensation of Aqueous Solutions, pg. 39
and Temperature Compensation (Tempco) and
TDS Derivation, pg. 43.
