Usually ships within 2 business days
Price: $995.00
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:
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.
To learn more about these competitive differences, download the PIECAL 434 vs Altek 434 sheet.
What's Included:
The PIECAL 434 gives you the ability to:
