The PIECAL 434 is a 4-20 mA loop calibrator you can use to check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DV loop.

The PIECAL 434 gives you the ability to:
  • Calibrate Milliamp Instruments - Source & Read 0.00 to 24.00 mA & -25.00 to 125.0% of 4-20 mA; Simulate 2-Wire Transmitters Power & Read 2-Wire Transmitters; Selectable 250 W resistor for HART compatibility
  • Calibrate with Confidence - Accurate to (0.05% of Reading + 0.01 mA)
  • Compact & Affordable - Pocket sized with built-in belt clip & attached test leads
  • Faster Calibrations - Instantly select three outputs with EZ-CHECK switch & two speed EZ-DIAL knob

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.

PIECAL 434 vs. Altek 434
In comparison the PIECAL 434 improves upon other popular loop calibrator brands, such as the Altek 434, by including a larger display with larger digits, a bar graph, rugged switches, belt clip and a battery compartment for quick battery changes.
