Product overview
N O T I C E
Always disconnect power to the meter when electrodes are changed. Only use the meter as instructed in this
manual or the meter performance can decrease.
The H-series handheld and benchtop meters operate with glass sensor electrodes with BNC
connectors or non-glass probes with ISFET (ion sensitive field effect transistor) silicon chip sensors.
The meters use one pH electrode (a BNC pH electrode or an ISFET pH probe) at a time. When the
meter power is set to on, the meter automatically identifies the type of electrode that is attached.
The H-Series meters are available in eight models:
•Waterproof handheld meters with Bluetooth™ technology. Refer to Figure 1:
• H160G—pH and ORP
• H170G—pH, ORP, conductivity, TDS and salinity
• Benchtop meters with a USB output. Refer to Figure 2:
• H260G—pH and ORP
• H270G—pH, ORP, conductivity, TDS and salinity
• H280G—pH, ORP, conductivity, TDS, salinity and dissolved oxygen (DO)
• Benchtop meters with Bluetooth™ technology and a USB output. Refer to Figure 2:
• H260GB—pH and ORP
• H270GB—pH, ORP, conductivity, TDS and salinity
• H280GB—pH, ORP, conductivity, TDS, salinity and DO
Note: The difference between the benchtop meters is that the GB benchtop meters have Bluetooth™ technology
and a USB output, and the G benchtop meters only have a USB output. Unless noted, when the benchtop series is
documented in this manual, the benchtop meter includes all of the H-series benchtop meters (both the G and the
GB benchtop meters).

ISFET pH probe maintenance
CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
The expected life of an ISFET probe is approximately 18 months. The reference electrode has a KCI
gel that is diluted over time. The reference is sealed and is non-refillable. Replace the probe when it
becomes difficult to calibrate.
•Keep the probe dry with the protective shroud on when not in use.
• Clean oil, fat, food particles, starch, protein or other materials from the probe tip after use.
• Never use sharp metal objects (e.g., a needle, a pin, etc.) to clean the sensor surface.
• Remove the probe from environments with static electricity. Electrostatic discharge (ESD) can
permanently damage the probe.
• Remove the probe from environments that will damage the sensor, such as hydrofluoric acid or
abrasive samples.
English 15

• Remove the probe from environments that will damage the epoxy materials used in the probe tip
(e.g., keep the probe away from acetone, toluene, methylene chloride, xylene and other strong
organic solvents).
•Do not use the probe in temperatures more than 60 ºC (140 ºF). Thermal cycling can decrease the
life of the probe.
• For semi-solids use, carefully twist the probe to make sufficient contact with the sample to the
sensor.
• When semi-solids are tested, make sure that solid objects (i.e., bone or gristle) do not scratch the
sensor.
• Cool samples to room temperature to maximize probe life.
• Always use new buffers and new rinse solutions.
Prepare the probe for storage
N O T I C E
Do not use the probe for long-term pH measurement applications.
Note: No electrode storage solution is necessary.
A new probe usually has visible reference gel at the tip of the probe, as well as in the interior of the
rubber dust cap. To remove the gel, carefully clean with a soft-bristled toothbrush and mild soapy
water (a few drops of dish soap in a warm cup of water). The gel can continue to show for two to five
days. Do not put the rubber dust cap on the probe until all of the reference gel is removed. Do not
complete the steps that follow until all reference gel is removed from the probe and the interior and
exterior of the rubber dust cap.
Prepare the probe for storage
1. Put the new probe (or the probe that was in extended storage) in pH 7 buffer for at least
5 minutes.
2. Stir the probe in pH 7 buffer solution to dislodge air bubbles.
3. Use fresh deionized water to rinse the probe.
4. Dry the probe with a lint-free cloth.
5. Put the rubber dust cap back on.
6. Keep the probe in dry storage when not in use.
Calibrate the ISFET probe
Refer to Prepare the probe for storage on page 16 before calibration.
N O T I C E
Do not use the probe for applications that cycle between hot and room temperature samples.
Note: Remove other active or non-active measurement devices during pH or conductivity measurement. Other
devices, even AC power, can cause interference.
Note: Only do calibrations away from the sun. Direct sunlight can cause unstable readings or difficulty in
calibration.
1. Connect the probe to the meter.
2. Set the meter power to on.
3. Clean the probe with new deionized water and dry with a lint-free cloth.
4. Put the probe in the pH 7 buffer.
5. Clean the probe with deionized water and dry with a lint-free cloth.
6. Put the probe in the second buffer (pH 4 or pH 10).
7. Read the results.
8. If the result is not correct, the probe is not correctly hydrated.
Soak the probe for another 5 minutes in pH 7 buffer, then do the calibration again.
16 English

Clean the ISFET probe
N O T I C E
Do not use sharp metal objects (a needle, a pin, etc.) to clean the sensor. This can scratch the sensor and cause
permanent damage to the probe.
For use in dairy, cheese or meat applications, soak the probe in Pepsin Cleaning Solution for
15 minutes before the probe is cleaned.
Regularly clean a non-glass probe:
1. Remove the rubber dust cap from the probe, then rinse with new deionized water.
2. Use a soft-bristle toothbrush and a mild detergent (a few drops of dish soap in a warm cup of
water) to carefully clean the probe.
3. Rinse with new deionized water to remove all debris from the sensor surface.
4. Dry the probe with a lint-free cloth.
5. Calibrate the probe again. Refer to Calibrate the ISFET probe on page 16, then Prepare the
probe for storage on page 16.
Repair the ISFET probes
N O T I C E
Do not use the probe to find out if the buffer is above 60 °C (140 °F). If the probe is suddenly put into very hot
liquid, the probe can be permanently damaged.
Monitor how long the probes are in dry storage. If the probes are in storage for an extended period of
time, the KCI gel at the reference junction can crystallize.
1. Heat pH 7 buffer to approximately 45 to 60 °C (115 to 140 °F).
2. Soak the probe for 2 minutes.
3. Put the probe in room temperature pH 7.00 buffer and let cool.
BNC electrode maintenance
Prevent unstable readings:
•Keep the probe in an electrode storage solution.
• Start measurements with at least a 2-point calibration. Update often with 1, 2 or 3-point
calibrations.
• Use new buffers and new deionized rinse solution.
• Use buffer solutions with pH values no larger than 3 pH units apart. Ideally, the buffers bracket the
anticipated pH values of the unmeasured samples.
• Use deionized water to rinse residual buffer and sample solutions from the probe after calibration
and measurement.
• Calibrate at the same temperature as the sample solution. Although the meter has an ATC, get the
best results when the calibration buffers and the sample are the same temperature.
• Keep the connectors clean and dry. Dirty or damp connectors can cause unstable readings.
