Chemdose Manual
The Dramm Chemdose is a
machine designed for precision applica-
tion of chemical solutions directly to a
pot or root zone. This results in less
wasteful application of expensive chemi-
cals with little or no overdosing. The
Chemdose applies user defined amounts
of solution between 10 ml and 90 ml per
shot. Complete variability within this
range is possible. These shots may be
applied individually or may be released at
timed intervals. This is useful for dosing
to many plants in a small area and pre-
vents undue strain on the user's thumb.
For complete portability the
Chemdose is battery operated. The bat-
tery is a 12 volt 7 amp hour battery.
This battery may be recharged with the
included battery maintainer in approxi-
mately 6 hours. On a full charge, this
battery will allow for approximately
16,000 cycles or shots to be applied
before recharging is necessary. IMPOR-
TANT: Keep track of how many shots are
used on a charge as there will be no
warning when the machine needs charg-
ing. The Chemdose will continue to run
after 16,000 cycles but the volume of the
output will decrease, changing the preci-
sion of each dose. A cycle counter is
located on the control face of the
Chemdose to help with counting.
The Chemdose cart and tank are
designed to fit down standard green-
house aisles easily. The Chemdose
comes standard with 25 feet of co-
extruded polyurethane hose. This hose
is chemical resistant but not puncture
resistant. Be careful of all sharp edges
and corners when using the Chemdose.
The Chemdose gun has two buttons,
green and red. The green button will fire
one shot each time it is depressed. The
red button will activate the interval dos-
ing mechanism. Once depressed, the
Chemdose will continue to dose the pre-
chosen amount at the specified interval
until the button is depressed again. The
Chemdose includes an assortment of
three stainless steel dosing wands
designed for different uses: a 16", a 30"
and a 36" hanging basket wand. The 16"
wand is bent slightly at the end and is
designed for treatment of plants on
benches. The 30" wand is straight and
designed for treatment of plants grown
on the floor or ground. The 36" wand
has a 90˚ bend. This wand is perfect for
treating hanging baskets. The Chemdose
features a wand rack designed to carry
the two unused wands while the
Chemdose is in operation and all three
wands while the Chemdose is not in use.
