Zero Technologies, LLC - based in Bensalem, PA - has developed the ZeroWater Filtration System to  remove virtually all total dissolved solids (TDS). 

By removing virtually all TDS, ZeroWater  matches the TDS levels found in Purified Bottled Water.

ZeroWater filter has received certifications by NSF International and the Water Quality Association for the removal of copper, iron, zinc, aluminum, lead, chromium, mercury, chlorine and hydrogen sulfide.


TOTAL DISSOLVED SOLIDS

How do we test for TDS?

• water TDS testing like aquariums, swimming pools, water filters, and more
• Measurement range of 0-9990ppm and ±2% highly accurate and quick readings
• Data Hold Function: Freeze the measurement to view it out of the water
• Auto-off Function; Low power-consumption for years of reliable measurement
