Compensation
Menu-selectable choices provide the user with
a wide range of easily configurable selections
for temperature compensation.

Wide Rangeability
Analog output spans do not affect the display
range of -2.00 to +16.00 pH (-2000 to +2000 mV
for ORP and specific ion). Minimum and
maximum process variable output spans are 1.0
pH (100 mV for ORP and specific ion) and 14 pH
(3998 mV for ORP and specific ion),
respectively. Minimum and maximum temperature
output spans are 10 C (18 F) and 140 C (284
oo o
F), respectively.

Innovative User
Interface
Using four Smart Keys and a custom Liquid
Crystal Display (LCD), multiple functions have
been assigned to each key and are displayed at
the appropriate time depending on the
programming environment. This patent-pending
technology reduces the number of keys while
maintaining the maximum amount of
functionality and allows for the use of a
larger, more visible LCD.
Simple Calibration
One- and two-point calibrations are available
and smoothly guide the user through each
calibration step. Provisions for viewing and
modifying the sensor calibration data are also
included. Temperature calibration uses smart
calibration routines which determine the
appropriate adjustments based on previous
calibration data.
NEMA 4X/IP65
Housing
Suitable for corrosive environments, the
electronics enclosure is a corrosion
resistant, aluminum alloy. A chemical
resistant polyurethane powder coating provides
external protection.
Suitable for
Hazardous Locations
The TB84PH Advantage Series analyzer design
complies with industry standards for Division
2 and non-incendive installations
(certification pending).
Diagnostic
Indication
The custom LCD has dedicated icons which act
as visible indications of an output hold,
fault, diagnostic spike, and energized relay
condition.
