Introduction
Product Overview
The Barnstead DIamond TII is a tap-fed water purification
system designed to be simple to use and to provide
reagent grade water that exceeds ASTM Type II, and
NCCLS/CAP Type I standards. It uses a thin film compos-
ite reverse osmosis membrane with pretreatment to pro-
duce RO water that is then polished using a two-stage
deionization process combined with UV oxidation and a
0.2 micron final filter.
The % of the rejection between incoming and reverse
osmosis product water is monitored and an indication is
provided to the user if the RO water quality is unaccept-
able. Incoming and RO pressure are provided by pres-
sure sensors located inside the unit. The DI water purity
is continuously sensed by a resistivity cell and displayed
on a graphical display.
RO operation is automatic and works independently of the
DI system to fill the external reservoir as determined by
sensors in the reservoir.
The DIamond TII is not shipped with pretreatment and DI
polishing cartridges or a final filter. These must be
ordered separately. The start-up kit containing these
components can be ordered using part number D502138
for all units.
The electronics can be verified and calibrated utilizing a
N.I.S.T. Traceable Calibration Module. See accessory
ordering information.
Please read the instructions carefully to ensure that you
receive maximum benefit from the DIamond TII. Also,
please fill out and return the enclosed warranty registra-
tion card as it will help us assure you of proper warranty
coverage.
