Choose conductivity-only tools for straightforward checks, or select multi-parameter meters when TDS, salinity, pH, resistivity, mV, or temperature readings are also part of the task.
Compare format, features, and included components
Pen-style meters suit convenient point-of-testing measurements, while handheld meters and kits offer broader measurement options and may include electrodes, calibration materials, sample accessories, or carrying cases.
Consider the water-based system being tested
Represented applications include testing tap water and wastewater, plus routine monitoring in cooling towers, boilers, reverse osmosis systems, pools, and spas.
Plan for calibration and component maintenance
Calibration standards and buffers support measurement preparation. For existing equipment, confirm the replacement cell or electrode module is compatible and compare listed dimensions before selecting.
Listed range on represented compact conductivity pen meters.
One waterproof meter measures conductivity, TDS, salinity, and temperature.
Available on one waterproof pH and conductivity meter.
Known conductivity value available for checking and calibration work.

| Waterproof handheld meters and kits | Water-based testing where several values or organized accessories are needed | Available parameters include conductivity, TDS, salinity, pH, temperature, mV, and resistivity; select options include calibration materials, cases, memory, or a trend bar graph. |
| Replacement components and calibration solution | Maintaining compatible meters and preparing for routine checks | Confirm stated meter compatibility, component function, and dimensions; use the 1413 µS solution as a known reference value for supported calibration tasks. |
Plan the right fit before choosing
Select a format that fits where and how you test
Portable choices range from compact pen meters to waterproof handheld meters and complete kits. Pen meters provide a small handheld format for convenient readings, while portable kits and waterproof meters support field or worksite testing and may organize components in a carrying case.
- Conductivity pen meters offer readings from 0.00 to 19.99 mS/cm on represented models.
- A TDS pen meter adds total dissolved solids and temperature measurement.
- Waterproof meters support testing where water exposure is a concern.
- Portable kits may include an electrode, batteries, a wrist strap, or a carrying case.
Choose only the parameters your process requires
Conductivity is the central measurement across the category, but available instruments add different water-quality values. Multi-parameter options can reduce the need to carry separate tools when several readings are needed at the same testing point.
- Conductivity and TDS are available together on select portable meters.
- Some waterproof meters measure conductivity, TDS, salinity, and temperature.
- Select meters also add pH, with certain options including mV or resistivity.
- Automatic temperature compensation is available on select portable and handheld models.
Keep compatible equipment ready for routine work
The category includes calibration materials and replacement sensing components alongside complete meters. A 1413 µS standard solution provides a known conductivity reference point, while certain kits include conductivity standards and pH buffers. Replacement components should be selected by their stated compatibility, function, and dimensions.
- A 500 mL 1413 µS standard solution supports meter checking and calibration tasks.
- One pH and conductivity kit includes 84, 1413, and 12,880 microsiemens/cm standards plus pH 4, 7, and 10 buffers.
- Replacement options include a dedicated conductivity cell and a combined pH electrode and conductivity cell module.
- A conductivity cell is specified for use with EC600 and DO700 meters.
