TDS Meter - water quality test
Autoclave water test
The TDS Meter measures the amount of Total
Dissolved Solids in a solution. Since dissolved ionized
solids like salts and minerals contribute to the
electrical conductivity of a solution, a TDS meter
typically report the weight ratio between the dissolved
solids and the total weight of the solution. The unit
used by TDS meters is parts per million (ppm). For
example, a water sample of 1 kg containing 1 mg of
dissolved solids is equal to 1 ppm TDS.
The conductivity of water is usually
expressed as micro Siemens/cm (µS/cm) The relation
between conductivity and dissolved solids is
approximately 2:1. It is recommended that the process
water for an autoclave has a conductivity of no more than
15 µS/cm. The equivalent TDS reading would be 7.5,
a reading above that means the water is not suitable for

autoclave, monitor your water quality.
