Overview
Complete pH system: featuring P53 controller and PEEK Body, wide-range sensor
Model P53 pH and ORP Analyzer is a full-featured, easy-to-use instrument. The large backlit LCD graphic display shows the measured pH, process temperature, both analog ouput values, and relay status.
PD1P1 Sensor is a high performance, differential technique, PEEK body pH sensor with built in preamplifier and integral 4.5m ( 15 ft) cable. 1-inch NPT threads at both ends for pipe Tee or pole mounting. Range 0-14 pH and 32 - 205 ° F

Features/ Benefits
Large Backlit LCD Readout.
The large display shows measured pH ( or ORP) in 1/ 2-inch ( 13 mm) high numerals. The P53 can also display the process temperature, and both analog outputs. Display screen annunciators indicate relay " on/ off" status.
Universal-mount 1/ 2 DIN Case.
The P53 is housed in a 1/ 2 DIN, epoxy-coated, metal NEMA 4X case. Its hinged front panel provides easy wiring access. The supplied bracket and stainless steel hardware enable panel, surface, and pipe mounting.
Electromagnetic Conformance.
The analyzer exceeds U.S. and meets European standards for EMI and RFI.
Simple Interactive Diagnostics.
Built-in diagnostics continuously tests analyzer and sensor operation.
Multiple Language Capability.
All screens can be selected for display in English, French, German or Spanish. ( Other available languages can be substituted.)
" Menu-guided" Operation.
The large display, simple keypad, and logical menu structure make the P53 easy to use. Menu screens, containing up to six text lines, guide you through setup, calibration, operation, and test/ maintenance functions.
Passcode-protected Access.
For security, use the P53´ s passcode capability to restrict access to configuration settings and calibration to authorized personnel only.
GLI Differential Sensor or Conventional Combination Electrode Compatibility.
The Model P53 can be used with any GLI Differential Technique pH or ORP sensor, or any conventional combination electrode. The P53 accepts Pt 1000 RTD, Pt 100 RTD, or NTC 300 ohm thermistor temperature compensators.
Two 0/ 4-20 mA Analog Outputs.
Each of the two isolated analog outputs can be set to 0-20 mA or 4-20 mA, and assigned to represent the measured pH ( or ORP) or temperature. During calibration, both outputs can be held at their present values, transferred to preset values, or remain active to respond to the measured value.

Calibration Methods
2-point Buffer Method ( pH only) : Automatic calibration and buffer recognition using two buffers from a selected buffer set* .

NOTE: When using buffers that are not included in either analyzer buffer set, calibrate using only the Sample Method ( 2 or 1-point) .
2-point Sample Method ( pH only) : Enter known values of two samples ( determined by laboratory analysis or comparison reading) or two pH buffers.
1-point Sample Method ( pH or ORP) : Enter known value of one sample ( determined by laboratory analysis or comparison reading) , one pH buffer or, for ORP measurement, one reference solution.

NOTE: Each output can be assigned to represent the measured pH ( or ORP) or temperature. Parameter values can be entered to define the endpoints at which the minimum and maximum mA output values are desired ( range expand) . During calibration, both outputs can be selected to hold their present values, transfer to preset values to operate control elements by an amount corresponding to those values, or remain active to respond to the measured value.
