10. Use water and a soft cloth to clean contamination from the exterior surfaces of the
aluminum block and rubber pads.
11. Allow the sensor head and screen to dry completely.
12. Place the bead retention screen over the diffusion path opening, with the concave side up.
13. Gently push the edges down into the diffusion path.
Ensure the bead rentention screen is fully recessed in the diffusion path but completely
above the first RH sensor port, so it does not interfere with the leaf or the diffusion of
vapor into the upper RH sensor port.
14. Place the spring inside the leaf clip top and use the short hinge pin to hold it in place
temporarily.
15. Align the leaf clip top and spring with the leaf clip bottom.
16. Insert the hinge pin into the hinge hole, pushing the short hinge pin out the opposite
side. Ensure the hinge pin is flush with the sides of the leaf clip.
17. Replace the agitation bead.
18. Replace a new Teflon filter.
NOTE: The Teflon filter looks very similar to the calibration paper disk. Ensure to select a filter.
19. Replace the o-ring.
20. Fill the desiccant chamber with fresh desiccant.
21. Replace the desiccant chamber.
22. Recalibrate the sensor prior to taking new readings (Section4.1).
CLEANING MAJOR CONTAMINATION
If water is not effective at dissolving the contamination in the diffusion path, the leaf clip
assembly can be further disassembled and cleaned with alcohol. The most important
consideration is to make sure that the porometer sensors are not exposed to alcohol vapors
during the process.
1. Follow step 1 through step 7 from the above cleaning instructions to partially
disassemble the sensor head assembly.
2. Use a 3/32-in hex key to remove the two screws from the front of the aluminum block.
3. Firmly pull the aluminum block away from the rest of the sensor head. The aluminum
block should pull free from the black plastic sensor assembly.
4. Clean the aluminum block thoroughly with alcohol or other solvent and a swab or cloth.
In extreme cases, soak the aluminum block in alcohol to dissolve contamination before
scrubbing and rinsing.
NOTE: Do not allow the black plastic sensor assembly to be exposed to solvent vapors or the sensors can be
damaged.
5. Let the aluminum block dry completely.
