MODEL 54e pH/ORP

SECTION 1.0

 

DESCRIPTION AND SPECIFICATIONS

The Model 54e when configured as a pH analyzer, requires a dual (glass and reference) impedance pre- amplifier (patent pending). This preamp converts the high impedance pH glass electrode signal to a low impedance signal. The preamplifier may be located in one of three areas: 1) in the pH sensor for best per- formance, 2) in a remote junction box when process temperatures exceed 80°C (176°F) in submersion applications, or 3) in the analyzer when the distance between the pH sensor and the analyzer is 4.5 meters (15 feet) or less.

The Model 54e pH measures over the full range of 0- 14 pH. The current output may be calibrated to repre- sent any 1 to 14 pH span.

A two-point calibration is made by immersing the sen- sor in two different buffer solutions and entering the pH values. When two buffers are used, the micro- processor automatically calculates the electrode slope which is used for self-diagnostics. The electrode slope can be read on the display and manually adjusted. A one-point process standardization is easily accom- plished by entering the pH value of a grab sample.

The Model 54e when configured as an ORP analyzer, measures over a range of -1400 mV to +1400 mV in either the American convention (Oxidation Reduction Potential), or the European con- vention (Reduction Oxidation-Redox). Although tem- perature compensation is not used for ORP measurements, the process temperature is measured and displayed. Temperature measurement is made by an RTD located in the sensor assembly.
