Conductivity Measurement

There is nothing to mix or measure. Just open one sachet and your fresh solution is ready to use. Our sachets are perfect for the field and lab since no extra glassware or measuring devices are needed, and nothing needs to be washed. These single-dose sachets ensure that you have just the right amount of solution every time, preventing cross-contamination of your samples.

Salts, minerals and dissolved gases contribute to conductivity, meaning conductivity indicates the amount of dissolved materials in a solution. TDS can give you a fairly accurate measurement when comparing the status of a single source (such as NaCl), yet when comparing two different types of solutions it may be error-prone. Calibrate the meter using the same dissolved materials that are in the test solution.

It depends on the solution you are measuring. The effect of temperature is greatest in low conductivity (or low ionic strength) solutions. In most cases, there will be a 2% increase per °C for most aqueous solutions. However, organics have very different temperature curves.

The probe is the same for both, but a salinity meter has a correction factor applied to the reading. The correction factor takes the conductivity reading and converts it to ppm of a specific salt (which varies by manufacturer).

No. The cell constant may be different and pin configurations are typically different. The type of thermistor used for temperature compensation is also different.
