Outstanding Circular Chart Recorder Operation
The VersaChart Circular Chart Recorder prints brilliant 4 color trend lines, scales, and alphanumeric data on 12” plain paper charts, and at user-defined rotation speeds from 6 to 9999 hours. The Circular Chart Recorder prints all the time lines straight, rather than curved, and they are printed on even time intervals for improved readability and easy time determination. All the trend lines are synchronized so there’s no drag pen time offsets as in conventional multi-pen circular chart recorders.

Excellent Circular Chart Recorder Features
The VersaChart Circular Chart Recorder features two bright, easy to read, 40 character vacuum fluorescent displays which can show values in a variety of user configurable formats. The Circular Chart Recorder's math and totalizer functions allow accurate flow recording, and can be configured for open channel flow systems that have standard flumes and weirs. The VersaChart Circular Chart Recorder is also designed for user-friendly operation with its quick-select keys, easy to read display and easily replaced ink cartridge.

Circular Chart Recorder Versions to Meet Your Needs
The VersaChart Circular Chart Recorders are available in two versions; record only (with alarm outputs) and recording controller. The Circular Chart Recorder is capable of controlling any process from simple on/off to dual 4-20mA outputs with full PID on up to 4 loops. We have listed four different circular chart recorder models below equipped with some of the most desirable options. All our listed circular chart recorders include NEMA 3 enclosure with glass window, transmitter power supply for each input, a box of 100 12” charts with 100 divisions and all necessary documentation. Please call or email Global Water for other circular chart recorder configurations to best meet your needs.
