DESCRIPTION AND SPECIFICATIONS
• pH ELECTRODE DIAGNOSTICS warn user of the need for calibration or electrode replace-
ment.
• AUTOMATIC BUFFER RECOGNITION with stored buffer-temperature curves
(1054B pH only).
• NEMA 4X (IP65) WEATHERPROOF CORROSION-RESISTANT ENCLOSURE.
• NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.
• SPECIFIC PROCESS TEMPERATURE COMPENSATION for pH changes due to tempera-
ture (1054B pH only).
1.1 FEATURES AND APPLICATIONS
The Model 1054B Microprocessor Analyzers, with the
appropriate sensor, are designed to continuously measure and control pH, ORP, conductivity, percent concentration, ratio, resistivity, ozone, dissolved oxygen and total
free chlorine in industrial and municipal processes.
The Model 1054B is housed in a NEMA 4X (IP65)
weatherproof corrosion-resistant, flame retardant
enclosure suitable for panel, pipe or wall mounting. All
functions are accessed through the front panel membrane keyboard which features tactile feedback.
Measurement data may be read at any time; however,
settings may be protected against accidental or unauthorized changes by a user selectable security code.
The display indicates the measured value in engineering units as well as temperature, alarm status, hold
output and fault conditions.
The analyzer transmits an isolated current output which
is continuously expandable over the measurement
range for either direct or reverse action. A hold output
function is available for allowing manual control during
routine sensor maintenance. During hold mode the output will be at a preset or last process value.
In the event of one of the following conditions, the
analyzer will drive the output to a preset value in addition to displaying a fault code. The Model 1054B pH’s
continuous self diagnostics alert the user to the following:
With automatic buffer recognition, the analyzer recognizes the buffers, then calculates the electrode slope
using stored pH-temperature curves for ten common
buffers.
Dual alarms are a standard feature on the Model
1054B and are programmable for either high or low
operation. Alarm 2 may be programmed to activate in
event of a failure detected by the continuous diagnostics. Both alarms feature independent setpoints,
adjustable hysteresis and time delay action. A dedicated interval timer with relay is also provided for chemical
or ultrasonic cleaning.
The 1054B pH automatically compensates the pH
reading for process temperature changes. Automatic
or manual temperature compensation is keyboard
selectable. Additional process temperature compensation is available.
The Analyzer includes a 0.7 inch digital display available in LCD or LED format.
The Model 1054B can display the process temperature in °F or °C.

The Model 1054B pH Analyzer requires a preamplifier to con-
vert the high impedance pH glass electrode signal to a low
impedance signal. The preamplifier may be located in one of
three areas; in the pH sensor for best performance, in a remote
junction box when process temperatures exceed 80°C (176°F)
in submersion applications, or in the analyzer when the distance
between the pH sensor and the analyzer is 4.5 meters (15 ft) or
less. The result is that the pH signal may then be reliably transmitted from the sensor to the analyzer using standard shielded
4-wire instrument cable.
The Model 1054B pH measures over the full range of 0-14 pH.
The current output may be calibrated to represent any 1 to 14
pH span.
A two-point calibration is made by immersing the sensor in two
different buffer solutions and entering the pH values. When two
buffers are used, the microprocessor automatically calculates
the electrode slope which is used for self-diagnostics. This electrode slope can be read on the display and manually adjusted.
A one point process standardization is also easily accomplished by entering the pH value of a grab sample.
