In addition to periodic laboratory testing, we test the purity of every batch of our distilled water on a daily basis.

To do this we use the 'top of the range' Hanna HI991300 portable TDS and EC meter.

This enables us to accurately test the Electrical Conductivity (EC), Total Dissolved Solids (TDS) and pH

The HI991300 boasts a resolution of:

pH - 0.01 pH

EC - 1 µS/cm

TDS - <1 ppm

and automatic 2-point calibration.
