Buyer guide

How to choose a pH or conductivity meter

01

Parameters, units and expected range

List pH and conductivity separately, including the expected range in µS/cm or mS/cm. If reporting TDS, record the conversion factor required by your method. A conductivity-derived TDS result does not identify individual dissolved substances.

02

Match the sample to the sensor

Give the sample type, temperature and container dimensions, plus the existing meter and connector if replacing a probe. A milk sample, a viscous product and low-conductivity water can need different sensor designs. Confirm the exact electrode and meter combination before ordering.

03

A catalog example: HI98130

The Hanna HI98130 listed in our catalog combines pH, EC, TDS and temperature. Its EC range is 0.00 to 20.00 mS/cm with 0.01 mS/cm resolution. That resolution equals 10 µS/cm, so a buyer needing finer low-conductivity readings should specify that requirement before choosing this high-range tester.

04

Budget for the calibration supplies

Choose buffers that cover the expected sample pH and that the meter recognizes. Include the required conductivity standard, electrode storage and cleaning solutions, and replacement-sensor needs. Ask for lot, expiry and certificates where required; an included starter sachet is not a recurring supply plan.

05

Field use, records and receipt

Specify portable or benchtop use, cable length, power and the output format you need. Ask the quotation to separate the instrument, sensor, standards and any calibration service. On receipt, check the model and kit suffix, included items and relevant certificates against the order.

Include this in the quote request

  • Sample or process, expected pH and conductivity range, and measurement temperature
  • Required resolution and accuracy specification, units and any TDS conversion factor
  • Existing meter model, sensor part number and connector, or a complete new system
  • Portable or benchtop use, container size, cable length and data-export needs
  • Buffers, conductivity standards, storage and cleaning solutions; required certificates
  • Quantity, delivery province, required-by date and procurement reference or TOR if used

Common pH and conductivity meter questions

Should I choose HI98129 or HI98130?

Compare the EC range and resolution: HI98129 covers 0–3999 µS/cm in 1 µS/cm steps; HI98130 covers 0.00–20.00 mS/cm in 0.01 mS/cm steps, equivalent to 10 µS/cm. Both specify EC accuracy of ±2% of full scale. The high-range model does not offer finer low-range measurement.

Does 0.01 pH resolution mean ±0.01 pH accuracy?

No. Resolution is the displayed increment. For example, Hanna specifies 0.01 pH resolution and ±0.05 pH accuracy at 25 °C for HI98130. Compare both values and the conditions stated by the manufacturer against your method.

Can one instrument measure both pH and conductivity?

Yes, some models can. HI98130 is one catalog example, but the required ranges and sensor suitability still decide whether it fits. A combined tester does not make every pH electrode or conductivity application interchangeable.

Is a TDS reading the same as a chemical analysis of the water?

No. On a conductivity-based tester, TDS is calculated using a conversion factor. Document that factor when comparing results across instruments; use the relevant analytical method when you need the concentration of a particular substance.

Should I choose a portable or benchtop pH meter?

Start with where the sample will be measured. ST300 and FiveGo F2 are portable pH/mV examples; FiveEasy F20 is a benchtop example. Check the electrode, power supply, cable length and any data-recording requirements for the exact model. Portability alone does not establish accuracy, sensor suitability or conductivity capability.
