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)

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.
