Altek calibrator – no longer in production

Replace your discontinued Altek calibrator with a PIE calibrator

Replace your outdated, obsolete Altek calibrator with new technology from PIE. Added features such as back lit display, automatic stepping and simple menu design make the PIE easier to use. Find more RTD and thermocouple types to choose from in a smaller, lighter package. Add to that our patented troubleshooting tools and its obvious why PIE is the calibrator of choice for technicians.

Altek 334A
Altek 334 and 334A
  • 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 3 expensive 9V batteries. Calibration seals remain intact.
