RECYCLING
YSI is committed to reducing the environmental footprint in the course
of doing business. Even though materials reduction is the ultimate
goal, we know there must be a concerted effort to responsibly deal
with materials after they’ve served a long, productive life-cycle. YSI’s
recycling program ensures that old equipment is processed in an
environmentally friendly way, reducing the amount of materials going
to landfills.
• Printed Circuit Boards are sent to facilities that process and reclaim
as much material for recycling as possible.
• Plastics enter a material recycling process and are not incinerated
or sent to landfills.
• Batteries are removed and sent to battery recyclers for dedicated
metals.
When the time comes for you to recycle, follow the easy steps outlined
at ysi.com.
BATTERY DISPOSAL
The 1200 is powered by alkaline batteries which the user must remove
and dispose of when the batteries no longer power the instrument.
Disposal requirements vary by country and region, and users are
expected to understand and follow the battery disposal requirements
for their specific locale.
