Common Accessories

27423
 
27423 CPEC200/310 Scrub Module
 
The 27423 is used to provide a source of zero air (air that contains no CO2 or H2O) to the CPEC310 for zeroing the EC155 gas analyzer. More often, a compressed-gas cylinder of zero air is used for this purpose; however, the CPEC310 scrub module may be preferable in locations where acquiring and replacing gas cylinders is not convenient.

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.
34007
 
This replacement part is for any lost or broken feedthrough cap that comes with the CPEC310. The 34007 includes the cap and a screw to secure the cap to the CPEC310 main enclosure.
32127
 
he 32127 is a screen that prevents insects (such as mosquitoes or gnats) from entering the vortex intake. 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. The screen is made from 316 stainless steel.
 
The EC155 Heated Vortex Intake is designed to separate particulates from the sample flow and reduce condensation. This newer vortex intake replaces the old vortex intake design that was susceptible to cracking near the intake. While the cracking on old vortex intakes is just cosmetic and does not affect measurements, users may want to replace their old intake with this new one.

Note: EC155 units that were shipped after March 29, 2018, have the new vortex intake already. The 31693 is intended for customers with an older EC155 unit.

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.
 
The 27333 allows customers to send their EC155 or CPEC310 to Campbell Scientific and have Campbell Scientific perform a zero and span; an RMA (Returned Material Authorization) is required. The zero and span should be done when ambient conditions change significantly (i.e., seasonally).
