Graphtec WR3320A Linearcorder Mark VII

Description

The WR3320A Linearcorder Mark VII is a thermal writing pen oscillograph which has been designed to meet the standards required by even the most exacting of professionals, including government agencies all over the world. This is a proud testament to their reliability and legendary performance.

The Linearcorder Mark VII is capable of recording high-speed phenomena of up to 140 Hz, and can therefore be used for a wide range of applications from production sites to the laboratory. The WR3320A can be configured as a 1-, 2-, 3 or 4- channel recorder with amplitude of 80 mm. per channel or as a 2-, 4-, 6 or 8- channel recorder with amplitude of 40 mm. per channel, (40mm and 80mm channels).

The WR3320A boasts a frequency response of DC to 140Hz as the highest speed thermal writing pen oscillograph. Chart speeds can be set in seven steps in both the 5 to 500mm/s and 5 to 500mm/min ranges and thermal pens ensure crisp, clear traces.

Both roll and Z-fold paper can be used with the WR3320A. 100 meter lengths stock inside the recorder, while an optional Z-fold chart supply box with a take-up tray enables the use of 200 meter lengths. Roll paper can be rewound simply by pressing the REWIND switch, and an automatic roll chart take-up unit is available as an option.

Remote control functions such as pen heat on/off, chart feed start/stop, synchronization with an external pulse, output of paper-end signal, input of event marker signals, and input/output of time marker signals enable automated, unmanned operation.
