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

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 134 matches the Altek in fit, form and function with a few features bringing the design into the 21st century. It has a belt clip and low profile switches for protection in the field and a larger display making it easier to use in the plant. Instead of the two 9V batteries in the Altek the PIE uses four common “AA” less expensive batteries. The PIE has the same resolution and accuracy as the Altek with longer battery life letting you calibrate more instruments between battery changes.
