APERA INSTRUMENTS / PH60-HF / AI3729
PH60-HF pairs the portable meter with LabSen 835 for suitable strong-acid and limited-HF aqueous sample tests. This is a conditional electrode selection, not a claim of unlimited hydrofluoric-acid resistance.
Use the exact 835 chemistry and exposure guidance. The stricter US page wording is below 0.1 mol/L HF (2000 ppm), brief sample tests under one minute, and not continuous measurement. Confirm the whole method with qualified laboratory procedures.
LabSen 835
Supplied electrode
Replacement AI3239
0.01 pH
Meter resolution
Meter accuracy: ±0.01 pH ±1 digit
8-pin
Matched external connection
Not an ordinary BNC-only substitution
Choose by the sample and the supplied LabSen electrode. Each card opens that model’s product page; optional compatibility does not mean an extra probe comes in the box.
AI3723
Low-ionic / pure water
LabSen 805; sample handling matters.
AI3721
Wastewater / dirty liquids
LabSen 335; open-junction routine.
AI3725
Small sample volumes
LabSen 246-5; vessel and junction contact.
AI3733
Viscous liquids
LabSen 855; reference selected for the matrix.
AI3727
Salty / alkaline water
LabSen 845; pH, not salt concentration.
AI3731
Hot / caustic water
LabSen 865; separate probe and meter limits.
AI3729
Limited-HF sample work
LabSen 835; all chemistry/time bounds apply.
AI3735
Meat / solid foods
LabSen 765; blade-sheath sampling method.
KEEP EVERY QUALIFIER TOGETHER
LabSen 835 is the selected HF-specific membrane/reference configuration, not a generic interchangeable glass probe.
The stricter US product-page wording is below 0.1 mol/L HF (2000 ppm), not unrestricted concentration.
Under one minute and not continuous measurement, with all remaining method/temperature conditions confirmed.
These are manufacturer product-fit boundaries, not an HF-handling procedure. Do not drop the concentration/time qualifications or treat a marketing test-count example as a guaranteed service life.
PH60 meter body, LabSen 835 external pH/temperature electrode, CalPod solution organizer, pH 1.68, 7.00 and 10.01 buffers, 3M KCl storage solution, protective cap, instructions and carrying case. Four AAA batteries are factory-installed per the model’s preparation instructions.
The current US kit buffer set is pH 1.68, 7.00 and 10.01. Match that working set to your sample and calibration method; do not assume every specialized PH60 package contains the same buffers.
SAMPLE FIT BEFORE FEATURE COUNT
Keep concentration, contact-time, temperature and chemistry qualifications together. Do not infer resistance at an unreviewed combination of conditions.
Choose the exact 835 electrode and intended matrix. Broad meter pH range is not a chemical-resistance specification.
This is product-fit information for trained laboratories, not an HF-handling or cleaning procedure. Continuous use is not established.
HF-specific glass membrane and polymer reference; non-refillable. The open junction and its sample contact are part of the method, not a universal chemical-compatibility or maintenance-free guarantee.
The source page’s stricter below/under wording is used here. A pH range or a conditional marketing test-count claim is not a warranty of unlimited HF resistance or service life.
Before selection, confirm exact chemistry, HF concentration, exposure duration and temperature against current 835/kit instructions. Retain every condition together; do not turn a sample-test rating into continuous-monitoring permission.
Use the specified kit buffers and current instructions. Start at neutral as directed, then choose the appropriate additional points. Do not infer an included ORP or EC probe.
Keep glass and junction in contact with a representative sample, limit carryover, and wait for a stable reading under the defined method.
The current US specialized-kit manual specifies a PH60 display range of -2.00 to 16.00 pH, 0.01 pH resolution and ±0.01 pH ±1 digit meter accuracy. Those numbers do not by themselves establish probe-range, chemical compatibility or total method accuracy.
Temperature measurement/ATC is 0-100 °C in these current US kit instructions. A higher electrode-only temperature figure does not extend that electronic interval or validate every part of the assembly in the sample.
LabSen 835 0-100 °C in current US sources; HF compatibility cannot be generalized across every condition
The listed LabSen 835 is non-refillable. Its internal reference/electrolyte description is separate from the external 3M KCl storage vial. Do not open/refill the reference because a chemical name appears in a table.
Rinse before and after measurements without rubbing the glass. Use contaminant-specific manufacturer care rather than an improvised chemical recipe; after deep cleaning follow the required rehydration and recalibration sequence.
Store the probe in its tightly closed vial with the specified 3M KCl solution, not tap, RO, distilled or deionized water. Keep solution fresh and the connector clean/dry. A dry or poorly stored probe needs the model’s recovery routine before calibration.
Apera’s electrode-family introduction explains the general technology. It is not an exact PH60-HF operating tutorial; use this kit’s current manual for sample preparation, limits and care.
These are separate instruments for different water-measurement tasks, not substitute specialized electrodes for PH60-HF. A general-water meter link does not establish HF, caustic, hot-process or direct-food compatibility.

No. The US page positions limited-HF sample tests below 0.1 mol/L (2000 ppm), under one minute, and not continuous measurement. Those qualifications must not be dropped or treated as a universal compatibility guarantee.
LabSen 835, not 865 or 845. Use the exact HF-specific configuration; a mechanically compatible electrode is not automatically chemically compatible.
The current US kit set is pH 1.68, 7.00 and 10.01. A regional flyer showing 4.00 should not replace the actual US kit set.
PH60, LabSen 835, CalPod, 3M KCl storage solution, cap, instructions and case are listed, with installed four AAA batteries indicated by preparation. A generic PH60-E or ORP probe is not an additional inclusion.
No continuous use is established; the manufacturer limits this positioning to brief sample tests. Select a properly evaluated system for a different exposure pattern.
No. Electronic pH range, glass suitability, HF concentration, contact time, temperature and the rest of the method are separate considerations. No unqualified chemical-resistance guarantee is made.
No. It is non-refillable. Use the specified 3M KCl storage/conditioning routine externally and do not infer a reference-refilling procedure from electrolyte wording.
Use the linked current US PH60-HF manual and exact 835 guidance. The listing does not reproduce hazardous cleaning or HF-handling recipes. Replacement electrode catalog is AI3239 with 8-pin connection.
Review PH60-HF and its LabSen 835 configuration, then return to the price and ordering controls. Blue Tiger Scientific can help clarify exact kit, probe and method requirements before ordering.
APERA INSTRUMENTS, LLC warrants this instrument to be free from defects in material and workmanship and agree to repair or replace free of charge, at the option of APERA INSTRUMENTS, LLC, any malfunctioned or damaged product attributable to the responsibility of APERA INSTRUMENTS, LLC for a period of TWO YEARS for the instrument and SIX MONTHS for the probe from the delivery.
This limited warranty does NOT cover any issues due to:
Use the current US exact-kit manual for the supplied configuration and operation. The LabSen handbook is additional method/selection reference, not a replacement for those instructions. Each card opens a PDF in a new tab.
