TDS Meter - water quality test meter
Autoclave water test meter
105.05 Inc. GST*
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 use.
Don't let this happen to your autoclave, monitor your water
