GENERAL DESCRIPTION & INTENDED USE

Hanna Instruments® has designed an extensive range of flat surface, industrial pH probes intended for industrial process control when teamed up with the HI510 Universal Process Controller.

• HI1006-18 and HI1016-18 series designed for low conductivity or low-temperature process environments
• HI1006-38 and HI1016-38 series designed for extended pH range or high-temperature process environments
• HI1006-48 and HI1016-48 series designed for process environments where hydrofluoric acid is present

An integral temperature sensor measures water temperature and adjusts the probe signal over the specified temperature range.

The flat tip eliminates deposits that can foul the sensor and significantly reduces necessary maintenance. The PVDF body material is easy to clean and disinfect, and resistant to most chemicals (e.g. solvents, sodium hypochlorite), ultraviolet light, and fungal growth. Suitable for continuous measurement of pH required in applications such as urban wastewater treatment, industrial effluent treatment, and surface water monitoring, the probe (and accessories) can be installed directly in‑line, immersed in a tank, or in a flow cell. 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).

MAIN FEATURES

• Rugged, chemically-resistant PVDF body
• Specialized glass sensor for fast stabilization and accurate results
• 3/4” NPT external thread for mounting
• Built-in temperature sensor for measurement and compensation
• Matching pin helps avoid typical problems caused by grounding loop current
• Digital probe stores model, firmware, serial number, and calibration information

SERIES CONFIGURATION

• PTFE junction
  • Minimizing the potential for clogging and chemically resistant, PTFE is ideal for samples with high content of suspended solids or for high‑pressure installations.
• Ceramic junction
  • Porous, chemically resistant plug connects the reference electrode to the process electrically.
• LT glass
  • Suited for fast stabilization and accurate results at lower temperatures.
• HT glass
  • Suited for fast stabilization and accurate results at higher temperatures.
• HF glass
  • Used in aggressive applications that have fluoride ions (F¯<2 g/L, temperature <60 °C, pH>2) and require fast stabilization and accurate results.

PROBE DIMENSIONS & CABLE CONNECTION

• Align the pins and key then push the plug into the socket.
• Rotate the collar to lock in place.

Note: Probe connection (probe with integral DIN connector) and probe wiring (probe with attached cable) must be carried out with the controller disconnected from power.

INSTALLATION

General considerations

• Probes are easily installed using the 3/4” NPT external thread.
• 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 and membrane from strong flow to prevent unstable readings. In turbulent aeration basin installations, place the probe in a weir for more accurate readings.
• Do not install the probe in an upside-down position.
• Provisions must be made for the removal of the probe from the process.
• Consider probe accessibility for maintenance when selecting placement.

Typical installation examples with mounting accessories

• Accessories are sold separately.
• In-line mounting and flow-cell installation require that saddle and flow cell are completely filled with water.

CALIBRATION

HI510 Controller allows two types of pH calibration procedures:

• Standard calibration performed in standard buffer solutions
  • Hanna Instruments®: 1.68, 4.01, 7.01, 10.01, 12.45 pH
  • NIST: 1.68, 4.01, 6.86, 9.18, 12.45 pH
• Process calibration performed with probes calibrated in standards and installed in the process

Standard Calibration

Preparation

• On the controller, go to Channel setup, Probe settings to select required buffer group.
• Up to three pH buffers may be used for a calibration.

At least two buffers are required to determine a pH slope.

_ Note: _It is recommended to select buffers that bracket the expected process pH.

Procedure

One-, two-, or three-point calibration can be performed using buffer solutions selected from one of the two buffer groups. It is generally recommended to use 7.01 or 6.86 pH buffer as first calibration point. When the electrode is immersed into buffer solution, the controller automatically recognizes the buffer value.

1. Remove the protective cap.
2. Press the key then CAL virtual key, to enter calibration mode. The first suggested buffer solution “7.01 pH” (using Hanna® buffers) or “6.86 pH” (using NIST buffers) is displayed in the upper left corner of the screen.
3. Immerse the pH probe approximately 4 cm (1½”) into buffer solution and stir gently. The controller automatically recognizes the standard and the buffer value is displayed.
4. When the reading is stable, CFM is displayed. Press CFM to save. “Wait” followed by “Calibration point is accepted and saved” is displayed after the calibration point has been saved and accepted.
5. Select Next to continue with a two-point calibration.
6. Repeat step 3.
   • 4.01 pH buffer value is displayed flashing but it will change to the buffer used once recognized.
7. When the reading is stable CFM is displayed. Press CFM to save.
8. Select Next, when prompted, to continue with a three-point calibration.
9. Repeat step 3 using a third buffer.
10. When the buffer is recognized and the reading is stable, CFM is displayed. Press CFM to save calibration. “Calibration DONE” confirmation screen is displayed next. To save a one-point or two-point calibration, select Exit when prompted.

Note: One-point calibration evaluates electrode offset whereas a two‑point or three‑point calibration evaluates both electrode offset and slope.

Process Calibration

• A process calibration is a single point calibration, performed while the probe remains installed in the process.
• Users can adjust the measured process pH value (±0.5 pH) so that it matches the value determined with a reference instrument.

Preparation

• Use a calibrated portable meter and probe to determine the process pH value.
• Process controller and probe should have previously been calibrated with two standards (probe slope determined).

Procedure

1. Press the key then CAL virtual key to enter calibration mode.
2. Press Process, to enter process calibration.
3. Use the keys to adjust the value to the one determined with the calibrated portable meter.
4. When the reading is stable, CFM is displayed. Press CFM to save the calibration. “Wait” followed by “DONE” is displayed at the bottom of the screen.

Note: Process calibration evaluates electrode offset.

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.

Storage

• When the pH 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.
