Operation of 10” Side Mounted Recorders (RCDR320, RCDR321)
Side mounted Honeywell DR 4300 General Purpose Circular Chart Recorders are also
available with CARON chambers. This chart recorder uses reliable microprocessor
operation to generate dependable pen drawn analog traces on preprinted 10-inch (250
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.

cartridges will have to be replaced as required.
