Altek 434 Milliamp Calibrator | Replace it with the updated PIE 434

Altek 434 Milliamp calibrator – no longer in production!

The Altek 434 was designed back in 1998. The PIE 434 matches the Altek in fit, form and function with a few features bringing the design into the 21st century. It has a rubber boot and lower profile switches for protection in the field and a backlit display making it easier to use in the dark corners of your plant. Instead of the six “AA” batteries in the Altek the PIE uses just four common “AA” batteries. The PIE has the same resolution and accuracy as the Altek with longer battery life letting you calibrate more instruments between battery changes.

PIE 434 automated diagnostic calibrator detect hidden loop problems vs Altek 434 Discontinued - Suggested replacement PIE 434

Advantages of the PIE 434 Automated Diagnostic Calibrator over the Altek 434 Milliamp Calibrator

  • Larger Display with Backlight
    Easy viewing in dark locations
  • Easy selection of 250 Ω Hart Compatible Resistor
    No disassembly to move internal jumper
  • Find Loop Current Leakages
    Measure ground current leakage from faulty wiring, flooded conduit and corrosion bridges. Leakage appears as a Zero Shift and helps you decide if the transmitter needs calibration or if there is some problem in the loop wiring.
  • More Resistant to Accidental Damage
    Rubber Boot and Stronger Switches
  • Less Expensive Battery Changes
    Four versus six “AA” batteries
  • Includes Certificate of Calibration
    All PIE Calibrators come with a free signed and dated certificate. Altek’s come only with an unsigned Statement of Calibration Practices with a certificate of calibration available for an extra charge.

Looking for more than just an Altek 434 replacement?

The PIE 434 does everything the Altek 434 can do plus simple to use loop troubleshooting features. Calibrate smart transmitters with the built-in 250 Ohm resistor for HART® compatibility, high resolution to 0.001 milliamp and the the ability to check loop power supplies or batteries with built-in DC Voltage measurement range. Save time troubleshooting loops by using the Advanced Loop Diagnostics to find hidden loop problems caused by moisture and corrosion in junction boxes. This feature is only found in PIE Calibrators!

Why choose a PIE 434 instead of some other brand of milliamp calibrator? We are the same team that designed the Altek 434 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 for service on your Altek milliamp calibrator PIE has the most experience in calibration and repair of Altek electronic calibrators. Or, if it is time to upgrade or replace a failing Altek 434 calibrator, we offer a discount on a new PIE calibrator similar to the Altek that you are replacing – in working or non working condition!
