Altek 134-2 Milliamp Calibrator | Replace it with updated PIE 334

Altek 134-2 Milliamp calibrator – no longer in production!

The Altek 134 was designed back in 1981 and the Altek 134-2 in 1999. The PIE 334 matches the Altek in function adding the ability to read up to 99.99 DC Volts, adds a backlit LCD and a rubber boot. Instead of the two 9V batteries in the Altek the PIE uses four common “AA” less expensive batteries. The PIE 334 has the same resolution and accuracy as the Altek with longer battery life letting you calibrate more instruments between battery changes.

Advantages of the PIE 334 pocket sized milliamp loop calibrator over the Altek 134 milliamp calibrator

    • Larger Display with Backlight
      Easier to use in dark areas of the plant
    • Drives More Devices in a Loop
      Full 24 Volt supply versus 18 Volt supply
    • More resistant to accidental damage
      Rubber boot for protection from falls. Optional hands-free carrying case for added convenience.
    • Separate Battery Compartment
      No more removing housing with screwdriver to replace batteries. Calibration seals remain intact.

  • Why choose a PIE 334 or 334Plus instead of some other brand of milliamp calibrator? We are the same team that designed the Altek 134-2 and the Altek 334A and no other manufacturer has as much milliamp calibrator experience as PIE. PIE also manufactures a complete line of milliamp, voltage, thermocouple, RTD and frequency single function calibrators as well as multifunction calibrators matching and surpassing the Altek line of handheld calibrators. When it is time to upgrade or replace a failing Altek 134-2 calibrator, we offer a discount on a new PIE calibrator similar to the Altek that you are replacing – in working or non working condition!
