CM-1000
Product Overview
Thank you for selecting
the
CM-1000
multi gas sampling
data
logger.
The CM-1000 is designed to
simultaneously measure multiple gas concentrations
through sampling methods
. With long-term data storage,
the user can assess t
he previous records
. When
the
CM-1000 measures the gas concentration reaching the
alarm setting or higher, the data display and alarm functions are activated.
The
CM-1000 is equipped with
an RS485 interface for connecting to a computer for remote
monitoring. The
Multi Gas
Sampling
Data
Logger
can be used in
a wide-range of industries and applications.
