General Description & Intended Use

HI83141-1 is a portable, water-resistant meter designed to be paired with HI1230B combination pH electrode and HI7662 temperature probe for pH, mV, and temperature measurements. Optionally, the meter can be paired with HI3131B refillable ORP electrode (not supplied with the product) for accurate ORP measurements.

Main Features

• Two-point calibration (front panel calibration trimmers)
• Hand-strap on the bottom for a more secure grip
• Compact, heavy-duty, water-resistant instrument
• Ideal for applications that require a custom calibration point

Probe Features

HI1230B pH

• Durable, polyetherimide (PEI) resin body suitable for a wide range of applications and chemically resistant to many aggressive chemicals.
• Double junction reference. No silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.

HI7662 Temperature

• Build-in NTC Thermistor for automatic temp. compensation (ATC)
• Stainless steel
• RCA connector

General Operations

Battery Replacement

1. Turn off the instrument.
2. Remove the three screws on the back of the instrument to open the battery compartment.
3. Remove the old battery. Insert one new 9 V Alkaline battery in the battery compartment while paying attention to the correct polarity.
4. Close the battery compartment using the three screws.

Note: If the "BATT" tag is displayed blinking, battery level is too low and the battery needs to be replaced.

Connecting the pH Electrode & Temperature Probe

Align the HI1230B BNC connector with the socket and plug it in.
Rotate the locking shell until it clicks in place.
Plug the HI7662 probe RCA connector into the designated socket.

Turning the Meter On

Press the On/Off key to turn the meter on. Initialization screen briefly displays all the LCD segments followed by the battery status, alerting user to the remaining battery life.

Sensor Preparation & Conditioning

1. Remove the protective cap.
2. If the protective cap does not contain any liquid, pour HI70300 Storage solution into the cap.
3. Place it back on the sensor and soak for at least 30 minutes before use.
4. Rinse with tap water prior to Calibration or Measurement.

pH Calibration

For high accuracy, frequent calibrations are recommended.
Additionally, the pH range should be recalibrated:

• whenever the pH electrode is replaced
• at least once a month
• after testing aggressive chemicals

Preparation

One- or two-point calibration can be performed using one of the following standard buffer solutions: pH 4.01, 6.86 (NIST), 7.01, 9.18 (NIST), or pH 10.01.
When a two-point calibration is required, use pH 7.01 or pH 6.86 buffer as first calibration point.
Use pH 7.01 (HI7007) (or pH 6.86 NIST equivalent) for neutral samples, pH 4.01 (HI7004) for acidic samples, pH 10.01 (HI7010) (or pH 9.18 NIST equivalent) for alkaline samples.
For best results, use a rinse beaker and a separate calibration beaker for each buffer. Discard rinsing buffers after use.

Procedure

1. Connect the probes and turn the meter on.
2. Remove the protective cap and rinse the tip with first buffer being used for calibration (e.g. pH 7.01).
3. Place the tip of the electrode 4 cm (1 1/2") into correct buffer. Allow a few minutes for the probe and buffer to stabilize/to reach thermal equilibrium.
4. Press the CAL key. The calibration range is automatically recognized and the offset on-screen tutorial messages are displayed.
   
5. Press the TEMP key to read the buffer temperature. Take a note of the displayed value.
   
6. Press the pH key to take the pH reading. Stir gently.
   
7. Wait a few minutes and use the calibration screwdriver to adjust the OFFSET trimmer until it displays the pH value at the previously noted temperature. See pH Buffer Values at Various Temperatures table.
   
8. Press the pH key.
9. Rinse with second buffer being used for calibration (e.g. pH 4.01 or pH 10.01). Place the tip of the electrode 4 cm (1 1/2") into the second buffer. Stir gently.
10. Press TEMP key to read buffer temperature. Take a note of the displayed value.
11. Press pH key to take a pH reading.
12. Wait a couple of minutes and adjust the SLOPE trimmer until it displays the pH value at the previously noted temperature. See pH Buffer Values at Various Temperatures table.
    
13. Press CAL key. The pH calibration is now complete.

Measurement

1. Turn the meter on.
2. After initialization, battery status is displayed. Replace the battery if BATT tag is displayed blinking.
3. Connect the probe (pH or ORP) to the meter.
4. For accurate pH measurements, calibrate the meter for pH before use.
5. Place the tip of the electrodes 4 cm (1 1/2") into the sample.
   
6. Press the designated key to select corresponding measurement mode (i.e. pH for pH measurements, mV for mV or ORP measurements, and TEMP for temperature measurements).
   
7. Stir briefly and wait a few minutes for the measurement to stabilize. Measured value and unit tag is displayed for the selected parameter.

Note: If measurements are taken in different samples successively, rinse the probes between measurements to avoid cross contamination. After cleaning, rinse the probes with some of the samples to be measured next.

Warnings

If measured value is outside the parameter limit of the probe, the maximum or minimum value is displayed blinking.
