The WR3320 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 WR3320 can be configured as a 1-, 2-, 3-, 4- or 6-channel recorder with an amplitude of 80 mm. per channel or as a 2-, 4-,6-, 8-, or 12-channel recorder with an amplitude of 40 mm. per channel. (40 and 80 mm. channels).

Continuous Recording Up to 200 Meters

Both roll and Z-fold paper can be used with the WR3320. 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.

Multiple Remote Control Functions

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.

1 V d.c. Reference Voltage Output

Rear panel reference voltage output connectors enable easy calibration whenever plug-in units have been exchanged. The reference voltage output used for calibration is 1 V d.c.

What's in a Name?

The WR3320 was previously referred to as the WR3310. This is the same instrument - only the name has changed slightly, to keep up with our continuous quality improvements.
