APERA INSTRUMENTS / PH60-WW / AI3721
Wastewater, suspensions and emulsions ask more of an electrode than a clean buffer does. PH60-WW pairs the portable meter with the external LabSen 335 pH/temperature probe and its open-junction reference design.
Choose the dirty-liquid configuration for a suitable defined sample, then make cleaning and junction contact part of the routine. Open-junction design does not mean clog-proof or maintenance-free.
LabSen 335
Supplied electrode
Replacement AI3231
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.
A JUNCTION CHOICE, NOT A CLEANING EXEMPTION
The glass and reference junction need appropriate contact with a representative sample.
Residue from one sample can influence the next. Rinse and check response before blaming the matrix alone.
Open-junction design helps the application; it does not make 335 clog-proof or maintenance-free.
Choose the cleaning approach for the actual contaminants from the current instructions. Do not turn a general wastewater label into a universal chemical-compatibility guarantee.
PH60 meter body, LabSen 335 external pH/temperature electrode, CalPod solution organizer, pH 4.00, 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 4.00, 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
Use the probe with a representative sample and a cleaning/checking routine matched to the contaminants. Do not assume every waste stream has compatible chemistry.
Give the glass and junction appropriate sample contact. Residue and carryover can affect the next reading even when the previous value looked stable.
Use calibration and response checks to distinguish sample behavior from contamination. An anti-clogging design still needs maintenance.
Open-junction design with polymer reference electrolyte. The open junction and its sample contact are part of the method, not a universal chemical-compatibility or maintenance-free guarantee.
Clog-resistant design is not a promise that solids, oil or aggressive chemistry can never foul the electrode. Do not substitute a different junction or housing on the strength of a similar catalog photograph.
Rinse before and after samples, immerse as the manual directs with the junction in contact, stir briefly and hold still until stable. Keep the connector clean/dry and choose contaminant-specific cleaning from current instructions.
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.
0-80 °C electrode rating in current US sources; separate from meter/ATC range
The listed LabSen 335 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-WW 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-WW. A general-water meter link does not establish HF, caustic, hot-process or direct-food compatibility.

The working kit is PH60 with LabSen 335, pH 4.00/7.00/10.01 buffers, CalPod, 3M KCl storage solution, cap, instructions and case. Four AAA batteries are installed. Manufacturer kit catalog is AI3721; Blue Tiger’s existing SKU is preserved separately.
No. It is selected to help with challenging dirty-liquid reference contact, but manufacturer instructions still include cleaning and clogged-junction troubleshooting. No maintenance-free or clog-proof claim is made.
Apera lists those as intended applications for LabSen 335. Suitability still depends on actual chemistry, sample preparation and maintaining both sensing and junction contact.
No. The supplied configuration measures pH and temperature. Sample dirt or salt content is not an independently measured EC/TDS/salinity result.
No. The specified 335 is non-refillable. Its polymer reference description should not be confused with an instruction to add liquid to the internal reference.
The PH60 electronics specify ±0.01 pH ±1 digit with 0.01 pH resolution. Sample-method uncertainty, contamination and electrode compatibility remain separate from the meter specification.
Rinse and use manufacturer guidance for the specific residue; do not rub the glass or improvise aggressive cleaning. Rehydrate and recalibrate after appropriate deep cleaning as instructed.
Use LabSen 335, AI3231, with the matching 8-pin connection. Store in the specified 3M KCl vial solution rather than pure water. A different BNC probe is not automatically compatible.
Review PH60-WW and its LabSen 335 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.
