Overview
The AP200 is a complete, integrated CO2 and H2O atmospheric profile system. It measures carbon dioxide (CO2) and water vapor (H2O) concentration from up to eight intakes, which are normally spaced along the height of a tower to give a vertical profile. The AP200 is often used in conjunction with an eddy-covariance system to measure the storage term and provide you with a more complete measure of the surface gas exchange.
Key Advantages
Preprogrammed and low power

(8)15702
Polyethylene/Aluminum Raw Plastic Tubing, 0.250 in. OD x 0.040
The 15702 tubing is required for the sample intake assemblies. Order enough tubing to connect all of the sample intake assemblies to the bottom of the enclosure. Maximum roll length is 500 ft.
Orderable9922
20 AWG, 1-Twisted Pair Santoprene Cable
The 9922 is a 20 AWG power cable used to power a heater on the orifice of each intake assembly. The power cable is normally daisy-chained from the enclosure to all the intake assemblies (e.g. one cable connects the enclosure to an intake assembly, and then another cable connects that intake assembly to the next intake assembly, and so on). Select the total length needed and then cut the cable into smaller lengths on-site to do the daisy-chaining.
OrderableCABLEPCBL
2-Conductor 16 AWG Power Cable
One CABLEPCBL is needed per system; choose the -PT cable termination option. This 16-AWG, two-conductor cable has a Santoprene® jacket and stripped and tinned conductors.
Orderable38476
16 GB microSD Flash aMLC Memory Card
The 38476 is a 16 GB microSD flash-memory card designed for use in harsh conditions often presented by environmental and industrial applications in which customers require higher reliability, endurance, and performance but also seek a cost-effective solution to meet budget-planning requirements.
Orderable27158
2 GB microSD Flash SLC Memory Card
The 27158 is a 2 GB microSD flash-memory card. This card is designed for use in harsh conditions often presented by environmental and industrial applications. The card uses single-level cell (SLC) memory, which aids in its ability to operate over wide temperature ranges, consume less power, and provide a reliable data-storage medium through more read-write cycles.
Orderable41303-5A
6-Plate Solar Radiation Shield
The 107 needs to be housed in the 41303-5A, a naturally aspirated, 6-plate radiation shield. The 41303-5A can attach to a crossarm, mast, or a user-supplied pipe with a 1.0" to 2.1" OD.
OrderableRAD06
6-Plate Solar Radiation Shield
The RAD06 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. It also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C (~75°F)) and low wind speeds (< 2m/s (~4.5 mph)), providing a better measurement.
