STM_EVO Spark tester

homepage > Products > Spark tester > STM_EVO

The STM series is available in:

 

AC, alternating current, with a completely sinusoidal waveform, in the following models:

  • STM_EVO_1.0 adjustable frequency3 from 500 to 1000Hz
    SIF chooses to provide instruments with frequencies up to 1000Hz because systems with frequencies above 2kHz have problems due to cable capacity. Most Spark Tester manufacturers DO NOT SHOW THE FREQUENCY MEASUREMENT and in the case of capacity automatically reduce the frequency without informing the customer/operator. SIF measures and shows the frequency on the display and allows the customer to adjust manually the frequency..

 

DC, direct current, in the following models

  • STM_EVO_DC in direct current

 

The bead chains electrodes are available with length of 50 – 100 – 150 – 200 mm
(upper length or brushes instead of bead chains available on request).
