The
Piecal 334Plus is a 4-20mA Automated Loop Calibrator that builds on the Piecal 334 with advanced features unique to PIE calibrators. Easily find current leaks to ground, deteriorating & damp insulation or corroded terminals with patented loop diagnostic technology (US Patent # 7,248,058). Automated stepping (2, 3 or 5 steps) and ramping lets you set the 334Plus at one instrument and check any other point in the loop.
Get better calibrations with a five digit display to 20.000 mA. You can read the display in dim conditions with the built-in backlight. Additional improvements over 334s from other manufacturers include better long term stability, accuracy, reliability & ruggedness plus improved battery life.
PLUS the 334Plus exceeds the performance of many higher cost calibrators to meet today's most demanding requirements while maintaining the familiar, time proven reliability and ease of use of similar calibrators. The PIECAL 334Plus is the new milliamp calibrator standard!
PIECAL Calibrators Competitive Edge
PIECAL Calibrators are
designed and built by members of the same team that designed and built
the calibrators manufactured by Fluke under the Altek label.
