Frequently Asked Questions & Glossary
Q: How long does the sample pump last?
A: The sample pump should last about one year and the pump head should to be
replaced annually or when necessary. Use the RCEL pressure indicator on the front
panel to see if the pump needs replacement. If this value falls below 10 in-Hg-A on
average, the pump head needs to be rebuild.
Q: Do I need a strip chart recorder or external data logger?
A: No, the M100E is equipped with a very powerful internal data acquisition system.
Section 6.10 describes the setup and operation in detail.
