Advantages of the PIE 334 over the Altek 334 and Altek 334A milliamp loop calibrator

  • Backlit Display with Larger Digits
    Easier to read in dark areas of the plant
  • More Resistant to Accidental Damage
    Rubber Boot and Stronger Switches
  • Separate Battery Compartment with 4 “AA” Batteries
    No more removing housing with screwdriver to replace three expensive 9V batteries. Calibration seals remain intact.
  • Calibrate More Devices Between Battery Changes
    Drives more loop instruments at 24 Volts (up to 1200 Ohms) for entire battery life. The Altek 334 output voltage drops as the batteries run down.
  • Includes Certificate of Calibration
    All PIE Calibrators come with a free signed and dated certificate. Altek calibrators come only with an unsigned Statement of Calibration Practices with a certificate of calibration available for an extra charge.
