CT87LF low temperature
recorder, with CT87-J-NP
probe (included with the
CT87L models).
The CT87 Series temperature
recorder is a precision instrument
used to monitor and record
temperature on a 152 mm (6")
circular chart. The CT87 may be
carried as as portable instrument
or mounted in a fixed location. The
CT87 offers a variety of features
to meet any temperature recording
requirement. A combination of
3 temperature ranges and 3 chart
speeds provides a high degree
of flexibility. In addition, the chart
rotation may be set for single
or continuous turn operation as
required by a particular application.
To protect the data being recorded,
the CT87 uses an automatic battery
backup to maintain operation during
a power outage.
