VT200/VT220 units are versatile, general-purpose weight indicators, with a wide range of industrial and commercial applications. The eight key panels enable easy operation, calibration, and setup of the instrument. An integral printer interface allows easy, programmable, ticket formatting. Automatic date and time storage with the real-time clock option clearly documents all printout records The VT220 with the LCD display includes an internal rechargeable battery option for stand-alone autonomous operation. Enclosure selections include tilted, wall mount, and desktop arrangements. |
