The 27333 allows customers to send their EC155 or CPEC200 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).

Detailed Description

With time, the EC155 and CPEC200 gas analyzers can experience some drift in signal offset and gain, especially under varying environmental conditions. Thus, a zero and span procedure (i.e., a simple two-point calibration) should periodically be performed on the analyzer.

The zero and span is usually performed in the order of several weeks or months. Anytime there is a significant change in ambient conditions (e.g., change in seasons) or when the instrument appears to have drifted, a zero and span should be done.


This service is available for the EC155 and CPEC200.
