CO
2
syringe tester allows accurate testing of CO
2
levels. Includes 2 tubes.
Draw 100 cc's of you growing area's air into the syringe. Break off both ends of a glass reagent tube and insert the tube into the syringe with the arrow on the tube pointing away from the syringe. Now gently push all the captured air through the tube. Now examine the tube. Where the purple color stops and the white begins is a PPM number. That's the CO
2
count in your area. Yep, it's that simple.
