Operation of 12” Side Mounted Recorders (RCDR322, RCDR323)
Side mounted Honeywell DR 4500A Truline Digital Circular Chart Recorders are also
available with CARON chambers. This chart recorder uses reliable microprocessor
operation to generate dependable drawn analog traces and print its own 12-inch (304.8
mm) charts. The two-pen model accepts inputs from a temperature sensor and a
humidity sensor. The single-pen model records temperature only. The recorders are
housed in a molded case with a glass window, gray gasketed door which protects
internal components while allowing easy access to the chart.
Routine Maintenance:
The recorder does not require any periodic maintenance. However you occasionally
will have to clean the pen tip.
