Hanna HI700384P 6.44 ppt TDS Standard Sachets

Choose the solution for the job

HI700384P supplies the 6.44 ppt TDS calibration point in single-use 20 ml sachets. The value is 6.44 g/l, rather than 6.44 mg/l, so it is important to match the tester’s range and units.

Choose this standard for a meter whose TDS calibration procedure specifies 6.44 ppt, such as the HI983024. A TDS display is derived from conductivity using a conversion factor; this standard does not identify the individual dissolved chemicals in a water sample. It is not a photometer check standard.

Using a fresh portion

Select the correct EC or TDS calibration mode and use the point specified by the meter. Rinse the sensing area, immerse it to the required level, remove trapped bubbles and allow the temperature and reading to settle. Follow the standard label and meter instructions for temperature compensation.

Keep EC and TDS units in your records. A change of display unit or conversion factor can change how the number looks without changing the sample itself.

Storage and related supplies

Keep unused solution sealed, check its batch and expiry details and avoid returning a used portion to the supply. Open a sachet when you are ready to use it and discard the used portion afterwards.

Compare the HI983024 TDS tester, the HI983124 EC/TDS tester, 12.88 mS/cm EC standard sachets to choose the format, measurement and care products that fit your instrument.
