The DR4500 circular chart recorder is a 12" digital circular chart recorder that delivers top performance to meet your process recording needs.

The DR4500 recorder comes in several models that address specific needs and markets.

The DR4500 Truline prints its own chart, recording up to four process variables on the same timeline, eliminating errors caused by temperature and humidity changes that affect the paper.

The HTST/pasteurization flow model (DR45AH/AP/AS) combines the broad capabilities of Honeywell's Truline recorders with the special features needed to record and control the pasteurization process.

The wastewater version (DR45AW) of the Truline provides the features required for industrial and municipal wastewater monitoring and recording, including Weir, Parshall flume and Palmer-Bowlus calculations.

The DR4500 classic recorder (DR45A1/DR45A2) uses the traditional fiber tip pens and pre-printed charts
