Is Hach's deionized (DI) water Type 1 or Type 2?
DI water type
The deionized water that Hach sells is Type 2.

Type 1 water is ultrapure water required for critical laboratory applications (Resisitivity >18 MΩ·cm). Common applications include HPLC, gas chromatography, cell culturing, tissue culturing, and mass spectrometry.

Type 2 water is used in general laboratory applications - it's pure, but not ultrapure (Resistivity > 1 MΩ·cm). Common applications include electrochemistry, sample dilution, radioimmunoassay and media preparation. It can also be used as feedwater to a Type 1 system.
