Hach P53A4A1N

Print
The P53 analyzer is a full-featured, easy-to-use analyzer. This versatile analyzer can be used with any GLI Differential Technique pH or ORP sensor, or any conventional combination electrode. 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. The display shows measured pH (or ORP), the process temperature, and both analog outputs. Display screen annunciators indicate relay "on/off" status. 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). The P53 is housed in a 1/2 DIN, epoxy-coated, metal NEMA 4X case. Its hinged front panel provides easy wiring access. The analyzer exceeds U.S. and meets European standards for EMI and RFI,and has multiple language capabilities.
Description
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.
