INTRODUCTION Thank you for purchasing this pH, ORP, or Conductivity Field Monitor. The Field Monitor Series feature microprocessor technology, which gives it many reliable, user-friendly features. These monitors were designed for long-term low- maintenance use. Just plug in the AC adapter, calibrate and the unit is ready for continuous monitoring.
CONNECTING THE PROBE The pH or ORP monitor uses any standard pH or ORP electrode with a BNC connector. The probe for the Conductivity monitor is hard-wired into the unit, no connection is necessary. NOTE: Keep connector dry and clean. Do not touch connector with soiled hands. 3.1 To connect the pH or ORP probe: Slide the BNC connector of the probe over the BNC connector socket on the monitor.
CALIBRATION This section is applicable for the following models: • Eutech Instruments: EC-PHFM1ST11 & EC-PHFM1ST21 • Oakton Instruments: 35623-00, and -05 only 4.1 Important Information on pH Monitor Calibration This monitor has 3 pH calibration points: 4, 7 and 10 with automatic buffer recognition.
4.2 pH Calibration 1. Plug in the pH monitor to turn on. The monitor will Immerse pH electrode into be in pH measurement mode. buffer solution, for example, pH 7 2. Rinse the probe thoroughly with de-ionized water or a rinse solution. Do not wipe the probe; this causes Press a build-up of electro-static charge on the glass surface.
ORP CALIBRATION This section is applicable for the following models: • Eutech Instruments: EC-ORPFM1ST11 & EC-ORPFM1ST21 • Oakton Instruments: 35649-00 and -05 only 5.1 Important Information on ORP Monitor Calibration Typically ORP measurements are taken on a relative basis and calibration is not required.
5.2 ORP Calibration 1. Plug in the ORP monitor to turn on. The monitor will Immerse ORP electrode into a calibration standard solution, be in ORP measurement mode. for example, 255 mV 2. Rinse the probe thoroughly with de-ionized water or Press a rinse solution.
CONDUCTIVITY CALIBRATION This section is applicable for the following models: Description Eutech Instruments Oakton Instruments Conductivity FMCON 1 with Conductivity EC-CONFM1ST11 35660-00 electrode and 110/120 VAC power adapter. Conductivity FMCON 1 with Conductivity EC-CONFM1ST21 35660-05 electrode and 220/230 VAC power adapter.

6.2 Conductivity Calibration 1. Plug in the Conductivity monitor to turn on. The Immerse conductivity electrode monitor will be in conductivity measurement mode. into a standard solution, for example, 4 mS 2. Rinse the probe thoroughly with de-ionized water or a rinse solution, then rinse with a small amount of Press calibration solution.
MONITORING Once the monitor is calibrated it is ready for monitoring. The monitor has two eyelet holes. Mount the monitor where it can be easily viewed. See figure below. Mounting Eyelets ENTER pH FM1 Continuous Monitor ELECTRODE CARE AND MAINTENANCE Since your pH/ORP electrode is susceptible to dirt and contamination, clean it every one to three months depending on the extent and condition of use.
8.2 pH/ORP electrode cleaning Salt deposits: Dissolve the deposits by immersing the electrode in tap water for • ten to fifteen minutes. Then thoroughly rinse with distilled water. • Oil/Grease film: Wash electrode pH/ORP bulb gently in some detergent and water.
