Use in an Indoor Garden
The SPC-2 is perfect for monitoring and controlling CO2
enrichment in indoor gardens and greenhouses. This unit
was specifically designed so the light emitted from
the LED
display and 'ACTIVE' indicator is not enough nor in the
appropriate spectrum to affect plant growth and/or plant
development
in any way. You do
not
need to cover these
light sources.
Description
Recommended for indoor use only. The SPC-2 is designed to easily
monitor and control CO2 enrichment. Just set it and forget it.
How the SPC-2 Works
The SPC-2 samples the air and determines the concentration of
CO2 in PPM. Then when indicated by your set point values (desired
PPM CO2 and elevation), the unit will activate equipment plugged
into either or the two outlets. The SPC-2 has a fixed hysteresis
(differential) of 20 PPM.
EXAMPLE:
With a CO2 set point of 1000 PPM, the unit will activate
(turn "ON") whenever concentrations fall below 1000 PPM and
continued to control and allow your CO2 equipment to enrich your
environment until it detects about 1020 PPM. The SPC-2 is a
reactive CO2 controller and the PPM concentration of CO2 will float
above 1020 PPM after defeating enrichment equipment (overshoot).
NOTE:
Depending on individual enclosure characteristics and air
circulation as well as location placement of the monitor this factor will
vary. The average swing for enrichment response is 50 to 100 ppm
which is actually a more desirable enrichment refresh frequency.
Safety Instructions
•
Mount unit on a wall or support structure using mounting parts
provided.
• Do not operate unit when wet and keep unit out of direct sprays
from foliar applications or irrigation moisture.
• Unit not intended for outdoor use.
• Do not service unit yourself. Breaking factory seal will void
warranty.
• If using an extension power cable, ensure the total ampere rating
of the equipment plugged in to the extension cable does not exceed
the ampere rating of the extension cable.
• Use a surge protector unit with a minimum of 850 joules.
• Do not operate while riding a Harley®.
