WELL EXACT
®
EZ ACCURACY
All tests have been calibrated using certi
fi
ed reference standards
and analytical spectrophotometric methods. The Well eXact
®
EZ has been factory calibrated and will stay valid because of its
exceptional quality. We are so con
fi
dent in the Well eXact
®
EZ, we
offer an industry leading 2-year warranty.
We built the Well eXact
®
EZ to be easy, accurate and
environmentally friendly. We have achieved this by utilizing our
patented eXact
®
Strip Micro Technology, which uses 60% less
water and chemistry than alternative methods. Instead of using
a 10mL water sample, eXact
®
Strip Micro uses a 4mL water
sample. The accuracy of the meter is maintained by designing
the sample cell with an 11mm path-length.
Ready Snap
®
3 is a calibration veri
fi
cation
solution with predetermined color to verify the
accuracy of your Well eXact
®
EZ photometer.
The easy 3 step procedure (snap,
fi
ll, and
test) allows for quick veri
fi
cation of test
parameters. Each box contains 10 ampoules
of 10mL solution with no dilution necessary.
