Conflict Minerals

Dart Sensors Ltd supports the ending of human rights violations in the mining of minerals from the area known as the “Conflict Region” in the Democratic Republic of Congo (DRC) and surrounding countries.

As such we require our suppliers to be “DRC conflict-free” and have undertaken due diligence to ensure that 3TG used in our products are sourced appropriately.

Transport of Products

We recommend that our products (whether installed in an instrument or not) are shipped in a sealed container to prevent the electrolyte drying out during transit.
