The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

EasyFlux PC
 
EasyFlux™ PC is a free computer program that processes high frequency time series data, collected using a Campbell Scientific eddy-covariance flux system, into fluxes following community accepted practices. Fully corrected fluxes of CO2, latent heat (H2O), sensible heat, and momentum are available, in generic, AmeriFlux, and GHG-Europe ASCII formats.
EasyFlux DL
 
EasyFlux™ DL is a free CRBasic program that enables a datalogger to report fully corrected fluxes of CO2, latent heat (H2O), sensible heat, and momentum from a Campbell Scientific open-path eddy-covariance (EC) system. Final fluxes are processed from raw high frequency time series data by applying commonly used corrections found in scientific literature.

Replacement Parts

33384
 
The 33384 contains two desiccant/scrubber bottles utilizing a non-hazardous molecular sieve. Each bottle contains necessary chemicals and membrane filters for scrubbing CO2 and water vapor from the gas analyzer housing. Empty chemical bottles should be disposed of according to local and federal regulations. SDS (Safety Data Sheet) forms for the chemicals are included in the EC155 manual.
3768
 
The 3768 is the two-pin power connector fastened to the EC155. It can be purchased separately to replace a lost or damaged connector.
 
The EC100-EB includes the EC155 electronics box and a Campbell Scientific CS106 barometer mounted inside of the electronics box.
CM250
 
The CM250 is a leveling mount kit for attaching the EC155 to a crossarm.
 
The 26570 is required to mount the EC155 closed-path gas analyzer and the CSAT3A sonic anemometer head to a mounting structure. The 26570 is an older style than the 32243 and is suitable for older CSAT3A anemometer heads. 
32243
 
The 32243 is required to mount the EC155 closed-path gas analyzer and the CSAT3A sonic anemometer head to a mounting structure. The 32243 is a newer style than the 26570 and better fits the new CSAT3A design. 
4905
 
The 4905 Single 4-Unit Silica Desiccant Bag is packaged in Tyvek. The supplied desiccant should fill the initial needs of most applications, but should be periodically replaced.
2207
 
The cable ties are constructed from a flexible, nylon material. A connection is made by pulling the tapered end through the locking end, thus forming a loop. The free end is pulled tight to secure the cables, then trimmed back to the locking end. Once attached, the cable tie must be cut to be removed.
26563
 
The cable is 4.5 m long. It may be purchased to replace a lost or damaged cable.
17492
 
The 17492 provides a 5/16" U-bolt and two nuts. This product is used to mount solar panels, mounts, enclosures, or sensors to a mast, tower, or pole.
8125
 
The 8125 is a small, flat-bladed screwdriver that is extremely useful for opening the guillotine terminals on our dataloggers and measurement control devices.
32203
 
The 32203 is a replacement in-line filter kit for the EC155 heated vortex. The kit includes a 25 µm filter and new ¼ in. Swagelok® nuts.
28698
 
The 28698 is a replacement intake filter (qty 1) and should be used for sites with excessive dust.
26072
 
The 26072 is a replacement intake filter (qty 1) and should be used for less dusty sites.
32127
 
The 32127 is a screen that prevents insects (such as mosquitoes or gnats) from entering the vortex intake of the EC155. This 1.27 cm (0.5 in.) diameter screen disc fits into the inlet of the vortex sample air cleaner. It is held in place with an interference fit and does not require adhesive or fasteners. It may be easily removed by using a needle or similar tool.
31461
 
The 31461 facilitates transporting the CSAT3A from site to site. The 31461 is offered as a replacement item for customers who do not have the foam that originally shipped with the CSAT3A.
33434
 
The 33434 is a carrying case without foam inserts that facilitates transporting the CSAT3A. The 33434 is intended for customers who already have foam inserts that were shipped with their CSAT3A.
27008
 
The EC155 Foam Case Set is typically ordered as a replacement part for the foam set that came with the original EC155. The foam set is designed to be used in either the EC155 carrying case or a cardboard box. This foam set protects the EC155 and its parts when travelling with the instrument.

Services

 
The 27332 provides a recalibration with zero and span. When drift between zero and span checks seems unstable, or when diagnostic output indicates a problem, the instrument should be sent in for a full factory calibration with zero and span. An RMA is required.
 
A zero and span should be done when ambient conditions change significantly (i.e., seasonally). An RMA is required.
