Altek 942 frequency calibrator – no longer in production!
The Altek 942 was designed back in 1996 and was last manufactured in 2015. The PIE 541 matches the Altek in fit, form and function with a few features bringing the design into the 21st century. Instead of the six “AA” batteries in the Altek the PIE uses a single 9V battery. The PIE has the same resolution and accuracy as the Altek with longer battery life letting you calibrate more instruments between battery changes. They both have ranges with high resolution in Hz and kHz as well as ranges for CPM (Counts-Per-Minute) and CPH (Counts-Per-Hour). A built-in BNC connector is available when the PIE 541-BNC is ordered.

Easy push button menu instead of turning the calibrator off and back on to change settings
- Simpler and easier battery changes
Single 9V battery vs. 6 AA batteries. Auto off feature saves battery life
- Smaller & lighter

Altek 941 or 942
Why choose a PIE 541 instead of some other brand of frequency calibrator? Like the Altek, the PIE 541 works with many different types of frequency instruments. We are the same team that designed the Altek 40, 40A, 241, 941 and 942 frequency calibrators and no other manufacturer has as much frequency 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.
