| Hanna Instruments Conductivity/TDS Testers |
Conductivity meters measure conductivity (EC) as expressed in "micro-Siemens"
or total dissolved solids (TDS) expressed in either parts per million (ppm), or parts per thousand (ppt), so you can determine solution
strength without regard to "buffers" and other chemical agents added to maintain
pH. Conductivity is important for water
conditioning and treatment, environmental, and electro-plating applications.
In hydroponic gardens and farming, greenhouses and aqua culture, measurement assures the
proper level of fertilizer is being dosed.
All units are rugged, pocket-size, battery operated (batteries are included), and have LCD
displays. They measure directly with no need to remove messy samples.

| Conductivity/TDS Testers |
We offer a variety of economical testers so that you will be able to select the unit best suited for your needs.
| Combination Conductivity/TDS Testers |
Hanna's line of combo meters gives you the ability to measure two or more essential parameters, using a single, reliable and economical instrument. All are waterproof and have replaceable electrodes for the primary usage.
| Calibration Solutions |
Calibration solutions are
essential to keeping your meter reading accurately and reliably. The bulb
in a pH meter is a semi-permeable glass membrane with a reference solution
inside. Over time, the reference solution changes, and the calibration
solution is used to adjust the meter to these changes.
There are three
common pH values: 4.01 (acid), 7.01 (neutral), and 10.01 (alkaline).
Two point calibration with 4.01 and 7.01 or 7.01 and 10.01 gives the most
accurate result But if the values you expect to read are right around one
of these values, you may be able to use just one.
A few drops of the storage
solution placed in the cap of the meter help to keep it moist, and minimize the
change to the reference solution.
