For our purposes, it's more than accurate enough. It takes all the guess work out of trying to figure how concentrated your CS solution is. This meter works equally well measuring standard DC CS or the high voltage AC CS such as Merlin's Super Silver mentioned above. These model TDS 1 meters with automatic temperature compensation are brand new and top of the line from Hanna Instruments, one of best names in laboratory measuring equipment. The meter comes with a sturdy, snap lid plastic case and jeweller's screwdriver for re-calibration if desired.
All units are factory calibrated and include calibration test results.
To test the unit, you can dip it in distilled water up to the max level indicated on the side on the meter. You should get a reading of zero. After measuring each CS solution sample, you should rinse with distilled water in between and when finished.
