OVERVIEW
The TB84PH Advantage Series is a line-powered
pH/ORP/pION (i.e., specific ion) analyzer with
state-of-the-art electronics, internal and
external diagnostic functionality, an
innovative user-interface having HotKey
capability, two user-selectable modes of
operation, and DIN-size packaging.
Diagnostic interrogation of the internal
circuitry and external sensing devices is
continually conducted to ensure accuracy and
immediate notification of problem situations
when they occur. Detection of sensor
integrity includes pH electrode damage, sensor
coating, sensor out-of-liquid, ground-loop
detection, and short/open sensor cabling.
Additional software functions monitor slope,
asymmetric potential, process variable
over/under range, and temperature over/under
range. If these diagnostic conditions occur,
the analyzer can be programmed to induce a
repetitive modulation of a given magnitude in
the output current or can be link to a relay
output thus providing the ability to alert
personnel of a problem condition.
The analyzer packaging conforms to DIN
standards and has mounting options that
include pipe, wall, hinge, and panel
installations. Due to the modular design of
the electronics, changing the analyzer sensing
capability to other analytical properties such
as solution conductivity can be quick and
easy.
The user interface is an innovative, patent-
pending technology which facilitates a smooth
and problem-free link between the user and
analyzer functionality. The programming
structure and multi-function keys reduce
programming difficulties by providing a toggle
between Basic and Advanced functions.
