Fowler Ultra-Cal III Series

The Ultra-Cal III series caliper represents the latest innovation in electronic measuring instruments. Designed and built by Sylvac of Switzerland, this gage uses a totally new, high accuracy sensor and durable optoelectronic interface. The optional computer connect kit enables direct connection to the computer's serial port without need for additional interface boxes or multiplexers. Using our data acquisition software, these calipers can feed your existing database, spreadsheet, and statistical applications.
