With the modular gas analyzer S700, a customer-specific and tailor-made measuring device can be put together for almost every application. 6 analyzer modules for the measurement of many more than 60 gases and 3 housing variants offer comprehensive and individually custom combination options.

Product description

The S700 modular system is very easy to configure to provide a tailor-made
application. An S700 housing can be equipped with up to 3 analyzer modules
for compact and cost-effective system solutions. A total of 6 different analyzer
modules are available for analyzing more than 60 gas components. Depending
on the measuring task, installation site, and ambient conditions, the following
housing types are available:
S710 19” rack for analyzer cabinets and standard applications S715 wall-mounting enclosure for harsh application conditions and zone 2 explosive
environment (ATEX) S720 flame-proof housing for zone 1 explosive environment (ATEX)

At a glance

• 5 different measurement principles available
