HK78D 6,000 Counts TRMS Manual Range Digital Multimeter
Product Description
The HK78D builds upon the HK78C’s functionality with advanced features for more professional use. Like the HK78C, it provides True RMS accuracy, a 6,000 counts display, and manual range selection, but it also adds LoZ AC/DC measurement to eliminate ghost voltages for safer and more reliable diagnostics.
Highlights
True RMS with 6,000 counts display
Manual range operation
LoZ AC/DC function to avoid false readings
Temperature measurement up to 1000°C (1832°F)
Square wave output (2000Hz, Vp-p >1.5V)
All-in-one electrical testing tool
