3 Preliminary Examination
1. PRELIMINARY EXAMINATION
Remove the probe from the packing and examine it carefully.
Remove the sensor's protective cap before use.
Each probe is supplied with quick reference guide with probe quality certificate.
Note: Save all packing material until you are sure that the probe works correctly. Any damaged or defective item
must be returned in its original packing material with the supplied accessories.
2. SAFETY MEASURES
General Safety & Installation Recommendations
•
Electrical connection, installation, operation, and maintenance must be carried out by specialized
personnel only.
The specialized personnel must read, understand, and adhere to the instructions in this manual.
•
Before connecting the probe to the process controller, disconnect the controller from the power line.
• User serviceable connections are all accessible inside controller’s enclosure.
• Before powering the controller, verify the probe wiring has been done following the instructions
detailed in this manual.
3. GENERAL DESCRIPTION & INTENDED USE
HI20X4-18 and HI20X4-28 are ORP and temperature probes designed for use with the Hanna Instruments®
HI510 Universal Process Controller. The system is designed to monitor and control disinfection chemicals or
follow and control a critical oxidation (or reduction) reaction.
mV measurements are auto-compensated for barometric pressure and temperature.
HI2004-18 and HI2014-18 platinum-sensor series are designed to provide the best response over a wide
range of applications.
HI2004-28 and HI2014-28 gold-sensor series are designed for oxidative processes.
The probe features a flat tip (ideal for solutions containing aggressive chemicals) which virtually eliminates dirt
deposits and significantly reduces maintenance.
Suitable for continuous measurement of ORP required for monitoring ond/or controlling oxidizers and reducing
agents in water treatment monitoring, industrial effluent treatment, and swimming pools, the probe can be
submersed/immersed using the 3/4” NPT threads, or installed directly in-line or in a flow cell installation, using
the lower sensor threads.
The probe is available with an integral connector that permits connections with no twisted cables as cables
are connected after installation.
Patch cables may be purchased separately to connect between the probe and controller up to 50 meters (164 ft).

8. INSTALLATION
General considerations
• Probes are easily installed using the 3/4” NPT external threads.
• Do not install the probe in an upside-down position.
•
Hand tighten the probe in position. Then, depending on the process, tighten one or two turns with a
wrench to secure in place. Do not exceed 10 N•m (7.3 lb-ft) torque specification for the probe sensor.
• Protect the probe from strong flow to prevent unstable readings.
• Protect the sensing surface from blunt objects.
• Make sure the sensing surface is kept clean.
• Provisions must be made for the removal of the probe from the process.
• Consider probe accessibility for maintenance when selecting placement.
7 Installation
Typical installation examples with mounting accessories
Accessories are sold separately.
In-line mounting and flow-cell installation require that the saddle and flow cell are completely filled with water.

The HI60501/HI60503 (PVC/PVDF submersible holders) and HI605011 (mounting flange) provide a sturdy
housing that prevents the probe from being damaged.
For high-temperature/complex chemical processes it is recommended the use of PVDF accessories.
To install the probe:
A. Unscrew the protective end cap (9).
The removable end cap allows for quick and simple probe maintenance and replacement.
B. Slide out the electrode holder cap (3).
C. Screw the probe into the internally threaded protective cap (9), step I.
D. Screw the probe and protective cap subassembly onto the holder (5), step II.
E. Feed the probe cable through the holder (5) and out through the cap (3) and cable gland on top (2).
The cable is shielded inside the holder to prevent any damage to the insulation.
F. Tighten the cable gland (2), step III, and slide the cap (3) back onto the holder (5).

10. CALIBRATION
ORP calibration is a single point calibration performed with the probe installed in the process or with the
probe removed from the process. Calibration point value can be adjusted ±60 mV around the measured mV.
Preparation
Probe removed from process
• Rinse the probe with deionized water and pat it dry with a lint-free cloth prior to calibration.
• Submerge the electrode tip (4 cm/1½”) into the sample to be tested.
11 Maintenance & Conditioning
• Do not let the probe touch the bottom or sides of the container.
• Remove the air bubbles from under the probe tip. Stir the sample at a slow to moderate rate and wait a
few seconds for the reading to stabilize.
Note: ORP calibration standards may be used with the probe directly i.e. 240 mV (HI7021 ORP test solution for
platinum and gold electrodes) or 470 mV (HI7022 ORP test solution for platinum and gold electrodes).
Probe installed in process
• Use a calibrated reference ORP meter and probe to determine the process value and write it down.
Note: mV measurements generated by the ORP probe are displayed with 1 mV resolution.
Procedure
1. Press the m key.
2. When the controller is in mV measurement mode, press CAL virtual key.
3. Use the ud keys to adjust the value.
4. After the reading has stabilized and the mV offset is inside the offset window, CFM is displayed.
5. Press CFM key to confirm and save the ORP calibration.
11. MAINTENANCE & CONDITIONING
General Maintenance
• Inspect, clean, and calibrate the probe at regular intervals.
• Inspect all connectors for corrosion and replace if necessary.
• Inspect the cable. The connection cable must be intact.
• Calibrate the probe after prolonged storage or cleaning.
• After use rinse the probe with tap water and dry it.
Conditioning
• Remove the protective cap.
• Shake down the probe to eliminate any air bubbles inside the glass bulb.
•
If the bulb and/or junction are dry, soak the electrode in HI70300 Storage solution for at least 30 minutes.
•
To ensure a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry.
Install the probe in such a way that it is constantly in the flow cell or the pipe is filled with the sample.
This will ensure a quick response and will keep the junction moist.
Cleaning
New probe
• Remove the protective cap.
• Rinse off salt deposits with water.
Probe removed from process
1.
Rinse the sensor in flowing water then clean by soaking in HI7061 Electrode cleaning solution for general
use for 15 minutes or use an application-specific cleaning solution.
2. Rinse with water and soak in HI70300 Storage solution for at least 30 minutes before reinstalling it.
3. Calibrate before use.
Accessories 12
In case of errors or faulty/fluctuating readings, gently polish the metal tip with a lightly abrasive paper, paying
attention not to scratch the surface. Follow with a thorough wash with water.
Storage
• When the probe is removed from the process for more than 1 hour, fill the protective cap with HI70300
Storage solution and tighten the cap on the sensor. Do not store the probe in distilled or deionized water.
