Operation of Thermal Side Mounted Recorders (RCDR314, RCDR315)
Side mounted Honeywell DR 4500 Truline Circular Chart Recorders are also available
with CARON chambers. This chart recorder uses reliable microprocessor operation to
generate dependable thermal traces on universal 12-inch (310 mm) charts. The two-
input models (RCDR315) accepts inputs from a temperature sensor and a humidity
sensor. The single-input model (RCDR314) records temperature only. The recorders
are housed in a molded case with a glass windowed, gray gasketed door which
protects internal components while allowing easy access to the chart.
