Hanna PWT Meter and Calibration Solution

Use the Hanna PWT meter to test your Colloidal Silver to see with reasonable accuracy what concentration you are actually making.

The Hanna PWT is the most economical way to get an accurate PPM concentration reading for Colloidal Silver. Hanna also makes a TDS meter that a lot of people use, but according to a lot of people the TDS meter is not as accurate as the PWT meter when measuring colloidal silver concentration.

To use the PWT meter correctly you need a bottle of Calibration Solution to accurately calibrate the meter. Without this solution your accuracy will vary widely and you won't get the results you expect.

Our PWT Meter bundle includes the Calibration Solution so you have what you need without having to order something else or hope your meter is calibrated correctly.

Please note: Once the calibration solution has been opened and used it can not be returned for a refund.
